The Mansion on O Street

Saves: 15
Check-ins: 14
This luxury boutique hotel was built in the late 1890s but was turned into lodgings in the 1980s. With sumptuous rooms and 70 secret doors and passages this is not only a place to lay your head for the night - it is an adventure. But it is an expensive adventure, the cheapest room will set you back at least $350 per night. (Photo by Pam Moran)
