"In the heart of Chelsea is The Cadogan Hotel, a collection of five connected townhouses where the doorman greets you in a bowler hat and the halls are filled with over 400 original artworks. (Including one Swarovski-encrusted peacock.) Like most London hotels, there’s quite a history behind it. This time, the stories are scandalous: one of the townhomes is the former residence of Lillie Langtry, a mistress of King Edward VII (at the time the Prince of Wales), and once upon a time, Oscar Wilde got arrested in room 118."
