I'm so glad that I came across The Mansion on O Street as a recommended "Thing to Do" in DC. Our family of two seniors and three adult children loved it! So different from any other experience we've had in our travels together. My only regret is that I chose a late event time (3 pm) so we only had about two hours to wander around. We all would have preferred to spend much more time there. We will definitely go back as a family and our adult children plan to go back with friends as well. So much fun!!

My second visit and brought my cousin Carol along with me, who also ended up loving it as much as I do! I also had the great fortune and pleasure to meet lady H who was a gracious and yet accessible hostess for the time that we were able to spend with her. Robert our young host / docent, made our visit that much more pleasurable! Not only was he able to help us with a couple of purchases that I made (which I shall cherish for a long time) he was charming, cheerful and knowledgeable about this amazing home, event space and boutique hotel as well!!
