Best Massage Spa London

Grace Belgravia markets itself as a members-only “health, wellbeing and lifestyle club”, but it also welcomes day visitors (who pay £150 per day for entry). High levels of privacy lure celebrities and models – don’t be surprised to bump into a Delevingne coming out of the shower – and the spa, though nothing extraordinary, is perfectly formed. There you’ll find eight treatment rooms, a nail salon, steam, sauna and relaxation area, but glide through a discreet door on the first floor and that's where Grace takes things to another level: GPs, medics and psychologists are on hand to tackle troubles and beat stress that can’t be resolved by a pampering session. Rigged up to vitamin drips, the lacklustre are given a new lease of life, or there’s hormone treatment and colonic irrigation available. Training sessions with fitness guru Matt Roberts and exercise classes are exclusively for members, but spa visitors can enjoy all the communal areas. Low-calorie Californian fare is served in Grace’s café, while the library is the place for people-watching.

Top treatment: Grace Intensive Cleanses include a medical consultation, dietary advice, personal-training sessions, a facial and other spa treatments and all meals. From £1, 950 (for a three-day programme) for non-members.
