I loved our espionage hunt and cannot believe I have lived in the DC area for three decades and have never been to the Mansion on O Street. I will definitely be bringing my future visitors here! The Mansion is truly one of a kind.

Came to visit my bf & we wanted to do something different & this was it! Really cool place with lots of history & so much to look at & through. My bf found a good handful of the secret doors! There was one place we were too scared to enter... but you'll have to go & find out yourself lol
