Even though it's one of London's largest hotels, the Churchill is always abuzz with guests smiling at the purring perfection they find here, including warmly personalized service and calmly alluring guest rooms. The shimmering lobby is in Robert Adamesque 19th-century style, and there's a hip connection with the Frieze Art Fair. There are two restaurants: Locanda Locatelli, one of best Italian restaurants in London, and the more traditional Montague, overlooking Portman Square. Guest rooms are lovely and modern, and suites are hung with cutting-edge art on loan from the Saatchi collection. No-nonsense business travelers and VIPs appreciate the highly convenient Portman Square location, and so will you.
