What began as a small inn in a 19th-century landmark mansion has expanded over the decades to include a contemporary section and hillside cottages, along with a full-service spa, all tiered down a hill in the center of Sausalito. The contemporary section contains newer rooms with wet bars, sunken tubs, and bay windows; some have balconies overlooking Richardson Bay. The hillside cottages are made for indulgence. Bay-view rooms are pricey, but the vistas are spectacular. In the newly restored Mansion, the ultraluxurious 5,000-square-foot Alexandrite Suite can be yours for $10,000 per night.
