Sofitel So Spa, London

There are luxury spas, and then there's Sofitel So SPA. Majestically situated in one of London's finest postcodes, this Grade II listed building serves up spa the French way. As you would expect, refinement and class are in abundance. This is translated into the design with glass covered walkways and sumptuous retail parlours decked out with regal-style furniture. In fact everything has been carefully considered: the lighting adds drama and ambience to the five treatment rooms, which are spread over three floors, while even the music is specially commissioned, as is the sweet scent that wafts delicately around the spa. The crowning glory is the expertise on offer. Using French skincare houses Cinq Mondes and Carita, the Gallic spa experience promises real results by harnessing a deluxe selection of treatments presented as a gastronomic menu of starters, mains and desserts - all provided by your very own Spa Butler. Bon appetit!
