Old Mansion, New Paradigm
The Mansion on O Street represents a future business paradigm- one in which there is maximum utility in every product, service, or idea that is sold.
The Mansion on O Street is a lesser-known Washington D.C. sight well worth visiting. It is a collection of five connected brownstone houses complete with five floors and five secret doors. The mansion is a combination hotel, extended stay residence, museum, antiques store, restaurant, and special event venue.
