Great fun! So much to look at! Turned out I wasn't very good at finding secret doors and passageways, although I did find a few. I left happily tired from exploring and will seriously consider a return trip, this time with some friends!

Our family had a blast searching the house for the secret doors! It was such a fun, unique way to spend time together with out-of-town guests. We'll definitely be taking more visitors to the Mansion on O Street.

My son and his family were at the museum a few weeks! They said it was so cool! The museum is just Amazing! Our visit was great! I love all the themed rooms with fabulous memorabilia! We found the wine cellar, secret rooms behind bookcases, and pictures. Staff were great answering and describing the museum. Highly recommend and will return next time when in DC.
