O Museum in The Mansion

Very cool and unusual space. Dozens of rooms from 4 apartment buildings combined together in a labyrinth of treasures. Definitely recommend to book tickets in advance. Takes around 2 hours to see most of the place and discover the secret doors. Not cold inside. Place functions as a hotel as well.

I was really surprised when I visited this place. I believe it’s made up of 5 row houses and each room is filled floor to ceiling with all kinds of memorabilia. We laughed at how crazy it was. It was fun trying to find secret doors (I think we counted 9) but w en funnier is that people actually book rooms there. It has the feel of an indoor flea market, not only because nearly everything there can be purchased, but because there’s so much old, random stuff. If you have an hour or so to kill and want to do something out of the norm and have a laugh, go for it!

Ok very interesting antique store and landmark. Not for young kids really. Don't bother with the special tours for "spies" etc - total rip off. But if you want a special shopping experience or want to see interesting musical memorabilia this is your place! To be fair, we did spend over 2 hours and the secret doors are cool!! Very "meow-wolfy" but much more authentic. This would be a really cool place for an adult dinner parté 😘😉

Family loved it, including wife and 2 boys 11 & 9. Kids loved secret doors. Wife loved secret rooms and exploring mansion, enjoying decor. Did not stay at property. Very unusual experience... Unique. Recommended!

Went to the O Museum in The Mansion for the tour. This tour included searching for hidden doors and gems through out the space. There are 70 hidden doors, but most that tour only find a small fraction of them. Normally less than 2. ;)
Spent a few hours exploring and was able to find a few doors and a few hidden gems. 14 doors, and 2 gems. The Rosa Parks room was fantastic, to actually be in a space that she lived for over 10 years was epic. The entire mansion feels like a huge thrift/antique store. It has a ton of books, toys, dishes, you name it. The space is fantastic. It is a lot of walking and a lot of stairs, although you can take the elevator to each floor. Overall this was the most enjoyable tour we took while visiting the Nation's Capital.

We visited the O Museum to explore the rooms and discover the hidden doors. We spent half the day searching for hidden doors, retracing our steps, and shopping for interesting items. We found 24 doors and were done for the day! We will return to search again. This is an amazing place to explore, enjoy, and relish what the O Museum has to offer those who enter. This is a hidden gem of Washington DC. You can uncover the hidden doors if you are willing to search and keep an open mind!

It's an interesting and unique experience and definitely different from your normal museum. I would recommend everyone try it out at least once. However, because of all the artifacts, it can be hard to find a flow so be prepared for possible sensory overload very quickly. Also, because there are so many aged things in an aged building, it has a very strong musty odor that made it difficult to breathe by the end of our 2 hour tour. I would strongly suggest they install dehumidifiers or something to that effect to help with the smell. Even opening some windows would help but it is definitely not a place where an asthmatic can feel comfortable much less stay overnight.
