The 18th century ambiance extends to the individual rooms: each one is decorated in a different style, with vibrant walls and eclectic period furniture. Room service is available 24 hours a day—don’t miss the cheeseburger and pommes frites, a must-have, or the menu’s animal-friendly section, “For The Pleasure Of Your Pets,” with special fare for guests’ beloved four-legged friends. There are a few on-site dining experiences as well, as in the Michelin-starred restaurant Le Chantecler or the more relaxed Le 37 Pop, both helmed by chef Virginie Basselot. La Rotonde Brasserie, which is currently closed for renovations, features a moving carousel with wooden horses. Après le dîner? Head to Le Negresco Bar, where live musicians take the stage most nights.
