What an adventure! So much to look at! The items all over the walls and in the rooms were fascinating. Such invaluable collections. And our group found six secret doors, which made us proud! Will definitely return!

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!
