We (family of 5) had a wonderful time! It was the perfect way to spend a blazing hot (100 degree) day. My kids were engaged and excited throughout our visit. This was a unique, memorable, and fun stop on our trip to DC!

MY 2 grandkids - 12 and 9 - absolutely loved it. They wanted to go back today. Looking for the hidden doors was such a thrill for them - one of the best things we've ever done together.

O Mansion is a hidden gem in DC that has been around for a long time. There are so many places for your eyes to go,I know that I have to go back again. And thanks for hosting a wonderful GoT series finale party! We had so much fun!
