This unforgettable luxury 5-star boutique hotel was built in 1901 and renovated in 2010, still maintaining the feel more of a traditional London club than a hotel. Located behind Buckingham Palace, from its chic black and white décor and rich mahogany furniture to the state-of-the-art technology and the thoughtful finishing touches, everything tells you that this elegant hideaway is in a league of its own. The hotel received TripAdvisor's Travellers Choice Award in 2009 and guests at 41 receive unparalleled 5 star service.

Staff here don't just know your name, they can recall your favourite drink, newspaper, and your favourite room. They can even remember what your pet likes to eat. You'll instantly feel at home in the cosy wood-panelled lounge with its roaring fire. Staff outnumber guests two-to-one, leading to an effortless stay and a high level of repeat visits. At turndown, staff place floating candles in the bath, spray lavender on your pillow, and turn your TV guide to today's page. You can eat or drink whenever you wish. There is even a pet concierge to ensure pets fees just as pampered.
