Very lucky to meet the owner of the O MuseumAt the elevatorAmazing hotelHighly recommended this historic hotel

Karen was wonderful & very helpful with suggestions in our search for the secret doors! .... we discovered 21 'verifiable' doors. Our group of 4 seniors had a blast for 3 hours exploring the house, and we will return. Thanks!!

Accompanied my two pre-teen grandkids to the O Museum and all three of us had a blast. Getting kids that age engaged (in anything not screen related!) can be tough, but the secret doors had them enchanted for several hours. Looking forward to a return visit next time I'm in the District. There is so much to see, it could never be boring. And the support for the arts is essential!

The Mansion is definitely a one-of-a-kind experience! Having found out about it on Atlas Obscura, I knew I had to visit. My wife, my brother, his wife, and their daughters all loved the challenge of finding secret doors, exploring the memorabilia in the house, and just generally exploring all the zany wackiness mixed with impactful history. We'd all highly recommend the experience to anyone visiting DC as well as to those who live there and may have never realized this little gem exists!
