This was a fantastic experience and very fun for my family. Be sure to allow at least two hours to go through the whole space. We could've stayed for three easily.

The museum was quite fun. We spent a few hours here exploring the different floors and rooms; trying to find the secret doors and passageways. I wish it wasn't quite so hot, and it was also hard to find parking. But would totally do it again!

Lightheaded and comfortable with a mix of ages helped make this a most enjoyable afternoon. Combined with the self guided tour beforehand is a wonderful way to relax and let the mind take a break from the world outside.

The Mansion on O street has been on my list for a long time and I was finally able to visit for a fun experience of searching for secret doors. It was a-ma-zing! We could spend hours there and not get bored so much to see. Kami, one of the employees was very sweet and friendly. She was very professional and welcoming. The entire experience was 5* thanks to all the friendly and approachable employees. I absolutely recommend visiting when you are in DC, this is such an off the beaten path thing to do.
