1. Dorchester Hotel Spa, London
The Dorchester Spa may exude an old-world glamour, but when it comes to treatments, it’s cutting-edge. Upscale Carol Joy London provides the facial treatments, while European skincare brand Kerstin Florian looks after the other treatments available in the nine sound-proofed treatment rooms. Double suites are available for couples, too.
