Claridge's

Spencer Tracy said he'd rather go to Claridge's than to heaven when he died. During the Second World War, the hotel housed so many exiled European monarchs — the Kings of Greece, Norway, and Yugoslavia among them — that it became known as "the annexe to Buckingham Palace." In 1945, Winston Churchill arranged for Suite 212 to be declared Yugoslav territory so that Crown Prince Alexander could be born on his own country's soil. The hotel traces its origins to 1812, acquired its Art Deco character in the 1920s, and has never lost its position as London's most discreetly glamorous address. 190 rooms in Mayfair. Maybourne Hotel Group.
