I love the O Street Mansion. I had a big birthday celebration for my most recent special birthday and have enjoyed several other activities there. Yesterday was no exception. The book talk was inspiring, the authors engaging, H.H. Leonards friendly and welcoming. All the staff was friendly and helpful. I had not known about Rosa Parks' connection to O St. and was moved by visiting her room and the video that was playing in it. Thank you for all your cultural and socially-relevant gifts!

I visited with a group from Loudoun County the previous week. I was so impressed that I returned Labor Day weekend with out-of-town guests. I knew they too would love the mansion.

I had such a fun time exploring the mansion and learning about its history. I've lived in DC for three years and wish I'd gone sooner. You could easily spend two to three hours visiting and still not find all the secret doors. Great for group events and solo excursions any time of year. The staff was also very friendly and helpful. 10/10 recommend.
