Honestly, this was the best activity my mother and I did while in Washington, DC. We were inside for 3hrs and still so much to see. Every detail, every item, was incredible. Definitely coming back with my children.

I have already contacted several friends and told them this is their next can't-miss destination in DC. We were fortunate to have gone when there was very little traffic and couldn't have had a better time. Absolutely fascinating. We found 12 doors in two hours! Can't wait to come back and find more.

Awesome experience! My team of 15 people absolutely loved it! We had a very comfortable private room with a snack that was upgraded to a full breakfast and we explored the mansion with a team building hunt. I highly recommend the Mansion on O Street for both team building activities and a family bonding experience :-)
