We had a great time during our visit! There was so many interesting things to see and learn about. We went for the hidden gems hunt but we ended up searching for the hidden doors also. A great time was had and we will definitely tell our friends to visit!

Fun spot for working as a team with your group. You must return it's no way to find a majority of the hidden doors in 1 day. Especially if the room is booked by someone staying in the boutique hotel. Hidden gem in D.C. for sure!

The museum was great fun! Lots of space to explore, & some very unique trinkets/artwork. If you're looking for a quirky excursion, this is the perfect spot!
