It was amazing - had never seen a house like this. So much too look at and then find hidden doors just added an extra excitement. Will return to take more time and see more.

I became so interested in the wood, glass, interior design, objects and artifacts that I almost forgot to look for the secret doors. What fun!!

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.
