The Hotel Duc de Saint-Simon is a classic choice for those seeking a traditional Parisian hotel with historic and romantic touches. It is said to be the place where Lauren Bacall stays while in Paris, which might help describe the guests who best fit in here: people of a certain age, with a certain budget. Rooms are not cheap, but the hotel sees many repeat visitors thanks to its great location on the Left Bank near Saint Germain and the Musee d'Orsay. The property is split by an outdoor terrace, and has a labyrinth feel on the inside with a series of small lounge areas. Head downstairs to the underground cave for breakfast or cocktails, and marvel at the oil paintings and Persian rugs. Comfortable rooms come in three sizes: Classic, Superior, or Suite, and -- like other areas of the hotel -- are decorated in rich fabrics and antique furniture (even the keys are antique). Room perks include flat-screen TVs, large bathrooms (by European standards), and plush bathrobes. Some rooms offer a private terrace or balcony, providing a nice spot to enjoy a glass of champagne from the hotel's impressive wine list.
