This place is so cool! It is a hidden gem in DC and we'll worth find. Ittaks hours to wander through and find doors as well as just take it all in.

What a hidden gem! This is a crazy, wonderful, secret hotel and museum. We did the Espionage Treasure Hunt, and really appreciated that it made us slow down and enjoy the space. Our family spent two hours, but easily could have spent the day. Love that the purchase of art and collectibles supports the arts. Our 19 year old son joined us. He is a difficult one to impress. He was impressed. Now we are hoping to book a room when we visit next year. The owners and staff were delightful people, as well.
