The Sanderson is an edgy Soho hotel with original and extravagant design by Philippe Starck. Innovative rooms feature a mostly all-white color palette, layers of sheer curtains that divide different areas of the room (in lieu of interior walls), and luxurious bathrooms, some with separate walk-in showers and freestanding soaking tubs. Beyond the rooms, the Sanderson seems to have one highlight after another, including an iconic lobby bar and a Mad Hatter-themed afternoon tea served in the striking courtyard. Travelers could also consider the whimsical Ampersand Hotel in South Kensington; the five-pearl boutique trades some of Sanderson's overt sexiness for more traditional elegance.
