London's famous smart and arty quarter centres on the King's Road, which has fun shopping, lively bars and clubs, and plenty of great restaurants from Michelin to sushi.  Chelsea is home to bankers, writers, socialites, actors and politicians.  The narrow streets running south to the river and north to Knightsbridge have some of London's most stylish places to stay: garden flats, boutique hotels, sumptuous duplexes and funky pads.
