Brown's Hotel London

One of the oldest hotels in London, Brown's was founded in 1837 and recently underwent nearly $40 million in renovations. Its mix of traditional (top-hatted doormen and a top-rated afternoon tea) and trendy (rooms with modern conveniences like wi-fi and a flatscreen TV positioned into the wall above the bathtub) appeals to well-heeled guests who want a prime Mayfair location set between London's most prestigious shops and Piccadilly.
