Hôtel Duc de St.-Simon
A jewel box of a hotel, the 34-room Duc de Saint Simon resembles a private Parisian home, with a black-and-white marble hall, graceful staircase, and rooms decorated in richly colored traditional French fabrics like toile de Jouy. Everything is so exquisitely appointed that the 18th-century memoirist and defender of the nobility after which the hotel was named would certainly feel at home here. Some rooms give onto the private garden in back, ideal for quiet contemplation. No wonder it has become a favorite among the famously private: Lauren Bacall, Anjelica Huston, John Irving, and Harvey Keitel.
Room to Book: Any of the rooms that contain the number 7, which are particularly prized for their location on the garden side of the building, or any of the four rooms with a private breakfast terrace.
