Rosewood London

Rosewood London lives in a beautiful Edwardian building off High Holborn, arranged around a grand courtyard, and its Sense spa carries the same sense of being a private house rather than a hotel. The dry sauna and steam room sit within a calm, low-lit thermal area that feels more residential than clinical — the kind of place you can happily lose an hour. The hotel itself is one of London's most quietly loved five-stars, with a famous staircase, generous rooms, and service that's warm rather than starchy. It's central without being touristy, grand without being stiff. For a heat session that feels like sweating in someone's very tasteful private home, it's lovely. Spa access for guests may involve a booking or fee for the thermal suite, so confirm what's included when you reserve.
