This 18th-century mansion, once the home of Cardinal de Retz, is just down the street from the château. You’ll pass through mighty gates and a grand courtyard before you enter the hotel, which is one of Fontainebleau’s most elegant. Rooms are decked out with antiques and reproductions, walls are covered with period prints, and the staff will make you feel that you are one of the Cardinal’s close friends. A Napoléon III-style bar completes the picture.
