We did this for our anniversary date and it was really fun! Finding all the secret doors is an adventure and the rooms are so interesting. Would recommend to anyone looking for something fun to do in DC!

Our New Year's Eve at the Mansion on O Street was enchanting. The blend of whimsical charm and curious elements created a perfect ambiance for celebration. The experience leaves us eager to return with more friends and family. Thank you for the excellent experience.

I loved everything about our evening here. O Mansion is a truly stunning place for people of all ages. It was the perfect location for a book launch. The guests enjoyed hunting for the secret doors and passage ways throughout the mansion fore the event started. The venue contributed to the wonderful success of the event as well. What a fun place to be!
