Famed designer Christian Lacroix has turned one of the oldest bakeries in Paris into a hip hotel with an artistic soul. While its 19th-century facade hasn’t changed since it sold baguettes, the inside now reflects the lovely, if idiosyncratic, world of Mr. Lacroix. Each room has a different constellation of colors, periods, and patterns that somehow blend together in elegant harmony. Some of the artwork on the walls is by the master himself. You can serve yourself in the cozy “honesty bar,” or between Thursday and Saturday the cool cocktail lounge opens to all (6–11pm). Guests have access to the spa and bicycles at the Pavillon de la Reine, which is under the same ownership.
