Fodor's Expert Review Hôtel Les Mars

This Relais & Châteaux property takes the prize for opulence with guest rooms, spacious and elegant enough for French nobility, furnished with 18th- and 19th-century antiques and reproductions, canopy beds dressed in luxe linens, and gas-burning fireplaces. Most of the white-marble bathrooms have spa tubs in addition to enormous showers. The 20-foot exposed-beam ceilings of third-floor Grand King rooms contribute to their palatial air; second-floor rooms have a slightly more understated style. The hotel, which has a restaurant and bar and a wood-paneled library off the lobby, has the feel of a sumptuous Left Bank mansion.
