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.

Great place to visit. Very unique and so much to see and read. Finding the secret doors and compartments alone can be extremely challenging. Some are obvious and others displayed as such. The restrooms are adorable and equally unique.Everyone should visit O-Street Mansion at least once!The parking situation can be pricey.Walkability: Extremely easy to get to on foot and parking distance.Noteworthy details: Everything in the mansion is for sale!

It was very interesting, a lot of visual stimulation, but a good experience overall
