It was so so so much fun!! Me and my friend had the best time. Definitely a must do in DC. Will for sure be again.

I'm so glad that I came across The Mansion on O Street as a recommended "Thing to Do" in DC. Our family of two seniors and three adult children loved it! So different from any other experience we've had in our travels together. My only regret is that I chose a late event time (3 pm) so we only had about two hours to wander around. We all would have preferred to spend much more time there. We will definitely go back as a family and our adult children plan to go back with friends as well. So much fun!!

A very interesting 2 hours of wondering around the O Mansion. There is plenty of stuff for everybody to see. We weren’t very successful at finding too many of the hidden doors..only 8 of 69 of the hidden doors
