A blast to look around at every room. The house is bigger than expected, with secret doors both somewhat obvious and completely inventive. I love that nearly everything is for sale.

We were in DC for a vacation but some in my group had to attend to a couple business activities. While they were doing that, 2 of us visited the museum and had such a great experience, we brought the rest of the group back later in the week. There are tons of really great experiences in the DC area, but the O Mansion is at the top of my list!

We had so much fun exploring the mansion with kids ages 11 and 14!

Every time that I visit I find something new. This is my third time, and I would definitely do it again.
