Everyone loves to discover a secret. This tour went above my expectations, and my children did not want to leave. Everyone was so welcoming, and the secret doors made us feel like winners every time we found one. Thank you for sharing your special home!

The Mansion is a remarkable location. A beautiful, totally unique experience combined with amazing hospitality. A National Treasure.

Surprisingly fun to explore and look. Kinda hated that we couldn't find all the hidden secrets, but by the end loved that it wasn't super easy and that there was more for the future.

I've lived in the DC area for 25 years and didn't know about the O Street Mansion/Museum. We found it through Groupon and I'm so glad we did! It is an amazing, fun place to visit and the staff are incredibly helpful and friendly. I can't wait to go back to try one of the other events and take friends and family so they can experience it as well.
