Popular with love-struck couples with friends on The Plateau, this renovated mansion is an ode to French Renaissance Revival architecture and promotes an organic vegetarian ethic. Its quiet and uncluttered entrance still has an original terra-cotta fountain, hardwood floors, and fancy moldings from 1890. Rooms are painted stark white and have broad, low beds. Claw-foot tubs and porcelain sinks—the taps say "hot" and "froid"—bring a smile to guests' faces. Another thing that brings smiles: all bedding and cleaning products are organic. The vegetarian Continental breakfast, also organic, includes hot options and yogurt, and guests are free to use the kitchen and its refrigerator (but only for vegetarian food). There's a new private terrace.
