This was one of the top things our family said they enjoyed while in D.C.! We all loved this experience from our 7 year old all the way to Grandparents. It was so much fun exploring and find the secret doors and passages! Our kids are already asking to return to try to find more doors! Our daughter had read about the O Street Mansion in her Treasure Hunters book and put it on her must see list while visiting.

Can't say enough about how cool the mansion is, we went in nearly blind, not knowing what to expect and we ended up spending over two hours. Incredible experience, with so much to see. It really feels like a magical place and an awesome date spot to take pictures in and explore together. Staff is so friendly and nice as well. We will definitely be returning to discover more!

This was a lot of fun exploring the house to find some of the hidden doors. We only found about 8 of the 70. It would have been nice to have some clues provided to help find the smaller ones. Overall, this was a fun experience and at a reasonable price.
