What a fun way to spend time with my adult kids in DC! We had a blast roaming the mansion looking for the secret doors and seeing all the treasures. We only wish we could have touched/handled the guitars but completely understand why one cannot. Thanks for a great afternoon!

We had so much fun that we are ready to come back. We were too busy looking around that we weren't looking for the gems. Next time, we would like to focus on the hidden doors.

This experience was an absolute blast! The Mansion on O is extremely quirky and charming. It's got an old, historic feel to it, and the place is littered with decades- or centuries-old items. The house feels like something out of a James Bond movie. Definitely a fun experience!
