Our favourite rooms
Room 11, a Townhouse Deluxe, clashes colours and cultures – turquoise walls with a red fireplace; a Buddha head in the grate and a repurposed Victorian carousel headboard – creating a vivaciously vintage-style space with clear views of London's skyline from the window and a dramatic black marble-panelled bath set into the wall. Families staying at the hotel will find more than enough room in the Townhouse Suite, which has a double sofa bed in the separate living room.
Some stamina, for a brisk bike ride over cobbles, bridges and docks in the day; and for exploring Farringdon's nightlife later on.
Room 2 is wheelchair accessible and the hotel lift goes to all floors. In-room spa treatments are available and there's no gym, but guests are given free access to LA Fitness in Holborn (a 10-minute walk away).
Only guide dogs allowed. See more pet-friendly hotels in London.
Welcome. For under-12s, cots and extra beds can be added to rooms free (subject to availability). Baby monitors are provided and work well enough here to allow parents a carefree drink at the bar and the concierge can arrange a babysitter on request.
The Zetter Townhouse Clerkenwell is remarkably forward-thinking, employing nifty gadgetry and schemes such as an energy loop (which heats your room and cools hotel fridges simultaneously), occupancy detection systems, water drawn from a borehole, and sustainable, recycled and environmentally friendly materials throughout. The Zetter is also a founder member of the Sustainable Restaurant Association.
