It is the people - the owners and Iso - that made me hesitant to write this review. They are good people. However... The Good: - The place we stayed was the townhouse across the street from the O Street Mansion. It was spacious and nice. The windows looked down at the street.

This place beats all I've ever seen! Crazy secret doors. Crazy stuff everywhere. I LOVED IT! We didn't stay in the hotel but went for dinner and a tour. The food was wonderful and the dessert bar was to die for! Then we were free to roam the house. Oh my gosh! You cannot

We went to O Street Mansion over Thanksgiving 2018 with our 13 year old girls. They enjoyed it, but not as much as we did. I loved the old Apple computer that was for sale. Everything is for sale there. The Beatles room and the Rosa Parks room were great. Plan to spend time

Hi JTSinDC! All of the treasure hunts are FUN. If they are into spies, intrigue and history they might like our Espionage hunt. If they love music they might like the Rock & Roll hunt. The Mustache hunt is also really fun and they get a mustache to wear :) . We also have a special hunt that has a different theme each month. Deciphering clues, searching for items, exploring our themed rooms and exhibits can take from 45 minutes to 2 hours depending on your group. Hope this helps. We look forward to seeing you!

Hi Amanda, The Champagne Tour is a self-guided tour. You will receive a glass of champagne and then you can go and explore our themed rooms like The Log Cabin, Safari room and John Lennon Suite and search for secret doors, signed guitars and much more on your own. The Mustache Hunt is a treasure hunt tour! You will receive clues to decipher that help you find specific items found only at The Mansion. Then you can also go and explore our themed rooms & secret doors. Both options are super fun!! We hope to see you soon.

"Don't stay, but if you are going to stay - stay in the townhouse across the street."
"Lots of themed rooms if you want to stay the night, but mansion also serves as museum for people who just want to look around."
"No matter what room you stay in, its like being in heaven."
"Many rooms to pick from. Each is unique."
"So many beautiful rooms; tell the receptionist what you love (the sea, French tea room, angels, jungles, etc.)."
