Mind boggling experience! Mansion stuffed with so much memorabilia it's hard to take it in all at once AND trying to find the secret doors! Would've liked a kids version with a little more help to find the doors. Fantastic, helpful staff and nice garden to enjoy a drink & snack.

This is one of the best kept secrets in DC! It is so wonderfully eclectic and quirky, and there truly is something in the museum for everyone to connect two. My only advice is to set aside a good chunk of time to explore (I'm talking 3-4 hours) so you can get the full experience. The staff was friendly and more than willing to answer any questions! I will definitely be back to explore more :)
