Treat yourself to a rub-down at one of London's most down-to-earth yet quality spas. Known for welcoming more than one celeb through their revolving doors, K Hotel and its basement spa has got star quality written all over it. In fact K Spa has pioneered a number of new techniques and innovations such as the Snow Paradise, a first for the capital which dips to -15C for spine-tingling stimulation, and the warming Scandinavian heat experiences. Unlike many celebs though K Spa isn't just about the superficial; delve into its array of inner and outer beauty treatments from CoffeeBerry, Crystal Clear, Germaine de Cappucini and exclusive brand Russie Blanche. Our highlight? We love the soft loungers in the chill out area called Kuddles that allow you to face your partner, yielding a more social and intimate experience.
