No. 11 London

A chauffeur-driven Rolls Royce Phantom is available to rent for a Heathrow pick-up; and guests are met by a butler when arriving at this family-run, private members club and hotel near Hyde Park. Owner interior designer Paul Davies restyled the four adjoining 19th-century Victorian townhouses in 2009, melding modern technologies like plasma screen TVs and free Wi-Fi with theatrical chandeliers, brocade upholstery and Louis XV-style furniture in its 60 guest rooms and suites.
