My sister , who has lived in Arlington for over 34 years, found the mansion online. We took my 15 year old granddaughter there. It was so much fun. We all loved the house. There is so much to see, and it’s all so interesting. We found 11 of the 70 secret doors. We spent at least three hours in the house. The owners are very nice. I recommend it to my friends, for a fun adventure

Madison, our event planner, was with me every step of the way. She was very responsive and knowledgeable. The Mansion on O St. is a great venue for meetings and events and adds a fun element for the group. We hope to return in the near future.

Our staff absolutely loved our time at the O Mansion. This was such a cool and unique place to spend our afternoon! The staff was so welcoming and friendly. I can't wait to go back and take my friends!
