The Matthew Williamson-designed garden is a real urban grotto: there are Moroccan-esque tiles on the floor, flowerbeds packed with brightly-coloured blooms and little round tables dotted here and there. It's open daily from 8am–8pm, for breakfast, lunch and pre-dinner drinks. The star of the show is a huge, glass, bird cage-like structure, filled with a table, lined with benches and strewn with patterned cushions. Guests who bag this spot will have the added reassurance of a glass roof to protect from the elements – always a worry in London…

Our favourite rooms
The Corfu Suite, which you enter from the garden; the Cardinal Suite (all in luscious reds); the Empress Josephine Suite with tented bed and a rich colour scheme of ebony and gold. If you're a book lover, try the grandiose librarian suite.
In-room spa treatments are available on request. The hotel also has membership of the nearby South Kensington Club, with its up-to-the-minute gym, spa, hairdresser and lounging areas.
You're in the heart of Chelsea, so some designer labels (to fit in with the locals) wouldn't go amiss. That being said, Blakes prides itself on making every guest feel at home, so whether you teeter in stilettos or traipse in flip-flops, no one will bat an eyelid.
Children very welcome; babysitters and nannies available on request (with 24 hours' notice).
The hotel are trying to reduce chemical and water use with a towel- and sheet-washing service on request only.
