Our staff absolutely loved our time at the O Mansion. This was such a cool and unique place to spend our afternoon! The staff was so welcoming and friendly. I can't wait to go back and take my friends!

This was the best experience. It is a must if you go to DC. Every room was amazing and the staff was superb. The challenge of finding the doors was exhilarating. I want to come back and stay there sometime.

My second visit, and we had an absolute blast, as always! Your commentator who introduced us to the Scavenger Hunt was energetic and well-versed in the mansion's history. Great job!

We had a wonderful time exploring this amazing hotel - we could easily have wandered the hotel for days!! Would highly recommend this very eclectic hotel. Spent quite some time looking for the hidden wine cellar, was definitely the highlight of our searches! Thanks for helping us celebrate our 40th anniversary in such a unique way. We will be back!
