In this guide
Five London hotels sell you a room with no window at all — not a bad view, not a light well, nothing. They belong to one operator, Zedwell, and they are the reason the phrase “windowless hotel” now means something specific in London rather than sounding like a complaint.
This is what you get, what you give up, and the one thing about the pricing that almost nobody explains.
💡 The Short Version: A windowless Zedwell room is a small, private, soundproofed hotel room with an en-suite rainfall shower and no daylight. For one person it is priced like any other central London room. For two or more it becomes very good value, because the second guest adds only about £5 a night. The rooms are cleaned every four days, and there is no kettle, no TV and no breakfast.
What you actually get
A cocoon room. Small, no window, and a door of its own.
Your own room, your own door, your own bathroom. The smallest is 7 sq m. The bed sits on a lit oak plinth, there is a full-length mirror, hooks rather than a wardrobe, and an en-suite with a walk-in rainfall shower.
The design is built around sleep rather than stay. Soundproofing on walls, floors and doors; purified, temperature-controlled air instead of an opening window; blackout by default because there is nothing to black out. The bathroom mirror runs circadian-rhythm lighting that mimics a daylight cycle, which is the closest thing to a window in the room.
Hypnos mattress, Egyptian cotton sheets, Wi-Fi over 50 Mbps. Reception is staffed 24 hours.
What you give up, beyond the window
These are the things that decide whether the format suits you, and none of them are on the booking page.
The room is cleaned every four days, not daily. Fresh towels come with that clean. You can pay for more, or collect clean towels and bedding yourself from reception at any time.
There is no kettle, no mini bar and no television, deliberately. No hairdryer or iron either — those are £10 to have delivered to the room. Piccadilly Circus and Tottenham Court Road have free beauty and ironing rooms; Greenwich, Knightsbridge and Park Lane do not.
There is no breakfast. Zedwell’s own answer to the question is a list of nearby restaurants.
Check-out is 10am and check-in is 3pm, which is a short day. Both ends move for money, and the West End sites charge properly for it:
| Early check-in from 9am | From noon | Late check-out to noon | To 2pm | |
|---|---|---|---|---|
| Piccadilly Circus, Knightsbridge, Park Lane, Tottenham Court Road | £60 | £40 | £50 | £80 |
| Greenwich | £25 | £15 | £25 | £50 |
After 2pm you are charged a full night at every one of them. Note what that £80 means on a quiet date: a late check-out at Piccadilly Circus can cost less than the room but more than a Cocoon 1 at Tottenham Court Road, so on a cheap night it is nearly a second night’s money for four hours. Greenwich is less than half the price at both ends, which is one more reason it is the value pick.
Foreign nationals must upload a passport copy before arrival, through a secure link emailed after booking. UK residents can check in with any government photo ID. This is the one that catches people out at 11pm.
The pricing, which works backwards
A windowless room for one person is not a bargain. Across five dates we sampled — a quiet Sunday, a February midweek, an October Saturday, the second Saturday of December and a Saturday in April — a single room at Zedwell Piccadilly Circus ran from £97 to £287. That is ordinary money for a central London room, and what you have given up is the window.
The value is in filling the room. The Cocoon number is how many people it sleeps, and the price barely moves with it:
| Date sampled | Room for one | Room for two | Difference |
|---|---|---|---|
| Quiet Sunday | £97 | £102 | +£5 |
| February midweek | £113 | £117 | +£4 |
| October Saturday | £253 | £258 | +£5 |
| December Saturday | £287 | £291 | +£4 |
| April Saturday | £168 | £172 | +£4 |
Four or five pounds for a second bed, on a room that swings by nearly two hundred across the year. Tottenham Court Road behaves the same way at £8 or £9.
It keeps going. A Cocoon 8 sleeps eight for about two and a half times the price of a single, and those ratios held to within about three per cent on every date we checked, whatever London was charging that week.
The catch is the beds. From Cocoon 4 upwards these rooms are built from double beds in bunks — a Cocoon 4 is two doubles, not four berths; a Cocoon 8 is four doubles. The per-person price assumes people are sharing a bed. Two couples in a Cocoon 4 is a genuinely good deal. Four friends who each want their own bed are not the customer that price is for.
Floor space works the same way: a Cocoon 8 is 20 sq m for eight people, against 7 sq m for one.
The five hotels, in the order we would book them
1. Zedwell Tottenham Court Roadad — the default pick. London’s first hotel entirely below ground, carved out of a disused car park beneath Great Russell Street, with 206 rooms. It undercut the Piccadilly flagship on every date we sampled, by £16 to £81, for the same product two Tube stops away. Two minutes from the British Museum and on the Elizabeth, Northern and Central lines, which makes it the easiest arrival from Heathrow. The only catch is that rooms stop at Cocoon 4, so a group of six or more has to go elsewhere.
2. Zedwell Greenwichad — the value one. The steadiest price in the group, and the only one where a February midweek came in cheaper than an October Sunday. A room for four starts at £117, and early check-in is £25 rather than £60. By the river for the Cutty Sark, the Observatory and the O2. You are trading Zone 1 for about a third off.
3. Zedwell Piccadilly Circusad — book it for the address, or for a group. The biggest and the most volatile: the price roughly triples between a quiet Sunday and a Saturday in December. It is the one to choose if you want to walk out into the West End, or if there are six, eight or twelve of you, because it is the only site selling rooms that big.
4. Zedwell Knightsbridgead — couples only. One room type, a Cocoon 2 sleeping two, so there is no single rate and no family option. On a quiet night it is the cheapest bed in SW1 by a distance; it reprices as hard as the flagship, so the bargain is a midweek-and-February proposition rather than a standing one.
5. Zedwell Park Lanead — a Mayfair address at Knightsbridge money. The newest of the five, underground like Tottenham Court Road, at 77 Park Lane, eight minutes from Marble Arch. It sells one room type, a Cocoon 2 sleeping two, which ran £90 to £207 across our five dates — within a pound of Knightsbridge on a quiet night and £50 cheaper on an October Saturday, for a W1K postcode. It is the least reviewed of the five, with only a handful of scores so far, which is the reason it is last here rather than the price.
Who should not book one
Do not book a windowless room if you want to spend daytime in your room, you are claustrophobic, or you are unsure how you react to sleeping without daylight. Two practical notes from guest reviews rather than the marketing: the rooms run warm, and the climate control is less individual than it sounds; and there is no daylight cue at all, so you wake to an alarm or you do not wake.
Reviewers split harder on this than on almost anything else in London accommodation. One group calls it the best sleep they have had in the city. Another finds it genuinely oppressive. Both reactions are common enough that neither is the outlier — which is the argument for booking one night before you book four.
Not the same thing as a capsule
Zedwell also runs two capsule properties, and confusingly calls the sleeping unit in those a “Capsule Cocoon” — so the word cocoon appears on both products. A capsule is a berth in a shared dormitory with shared bathrooms, at roughly a third of the price of a room.
The word to look for is “Capsule” in the property name. Our London capsule hotels guide covers those five properties in full, including what a night in one is actually like.
And if the reason you are considering a windowless room is a longer stay at a lower price, compare it with an aparthotel first: a kitchen changes the arithmetic more than a missing window does.

Zedwell Tottenham Court Road
££Accessible roomsCarved out of a disused underground car park beneath Great Russell Street - 206 soundproofed cocoons and London's first hotel that is entirely below ground.
Zedwell Greenwich
££Accessible roomsThe same soundproofed windowless format as the Piccadilly flagship, at Greenwich prices and within reach of the Cutty Sark and the Observatory.
Zedwell Piccadilly Circus
££Accessible roomsAlmost a thousand windowless, soundproofed 'cocoon' rooms above Piccadilly Circus, sold in sizes from one bed to twelve. The second person costs about £5 whatever the room costs, so the per-head price halves the moment there are two of you and keeps falling as the room gets bigger.
Zedwell Knightsbridge
££Accessible roomsAn SW1 postcode between Hyde Park, Harrods and South Kensington at a rate the area does not otherwise offer, two minutes from Knightsbridge station.
Zedwell Underground Hotel Park Lane
££Accessible roomsA Park Lane address at Zedwell money, one minute from Hyde Park Corner, and the brand's newest and most design-led property. Underground like Tottenham Court Road, so the windowless format is a fact of the building rather than a choice.
Common questions
Are windowless hotel rooms legal in the UK?
Yes. Building regulations require adequate ventilation and means of escape, not daylight, so a bedroom with mechanical ventilation and no window is lawful. Zedwell's rooms have filtered, temperature-controlled air rather than an opening window, and two of their hotels are entirely below ground where a window is not physically possible.
Which London hotels have windowless rooms?
Zedwell runs five: Piccadilly Circus, Tottenham Court Road, Greenwich, Knightsbridge and Park Lane. Every room in all five is windowless by design. Individual windowless or 'interior' rooms turn up in other London hotels too, usually as the cheapest grade in a converted building, but Zedwell is the only operator that does it as the whole proposition.
Is a windowless room cheaper?
For one person, not especially — a single at Zedwell Piccadilly Circus ranged from £97 to £287 across five dates we checked, which is ordinary central London money. Where it gets cheap is with more people in the room, because the price barely moves with occupancy. The second guest costs about £5 at Piccadilly Circus and £8 or £9 at Tottenham Court Road, whatever the room costs that night.
What are Zedwell's Cocoon numbers?
The number is how many people the room sleeps: Cocoon 1 through to Cocoon 12. From Cocoon 4 upwards the rooms are built from double beds in bunks — a Cocoon 4 is two doubles rather than four separate berths — so the advertised occupancy assumes people are sharing beds.
Do windowless rooms have a private bathroom?
Zedwell's hotel rooms do: an en-suite with a walk-in rainfall shower and a mirror with circadian-rhythm lighting that mimics a daylight cycle. This is the main thing separating them from Zedwell's separate capsule properties, where the bathrooms are shared.
Will I sleep badly in a room with no window?
Reviewers split about as hard on this as on anything in London accommodation. One group reports the best sleep they have had in the city — no traffic, no dawn, no thin curtains. Another finds it oppressive and would not repeat it. There is no daylight cue at all, so you wake to an alarm or you do not wake. If you have never tried it, book one night before you book four.
