Our favourite rooms
Each room has its own palette of hues and patterns; we loved blue and brown Room 2, although it’s on the ground floor, which isn’t the quietest. Large corner rooms 111, 211 and 311 on the floors above have the same colour scheme. Deluxe doubles facing the courtyard are romantic. For wonderful views of London’s rooftops, get one of the smaller top-floor rooms; 402 has low-slung windows, giving it a first-class Haymarket vista. Junior Suite 100 has outdoor decking.
There aren't many hotels in London that boast an 18-metre indoor pool as impressive as this one (if at all).
Bikinis or swimming trunks, so you can have a morning swim or afternoon dip in that gorgeous pool. An <i>A–Z</i> to help you navigate London's streets.
Her Majesty's Theatre is on the hotel's doorstep; there's a special afternoon tea for matinee-goers, or a two-course dinner deal for evening attendees.
Cots are free, and extra beds can be added to rooms for £66 a night. Babysitting costs £57.60 for two hours;£14 an hour thereafter. Games on request.
