The Spa at Mandarin Oriental Mayfair is an urban spa on Hanover Square, combining a 25-metre indoor pool with thermal facilities, personalised treatments and a strong emphasis on privacy and recovery.
Why visit
The heat-and-water facilities include a sauna, steam room, vitality pools and experience shower alongside the swimming pool.
