Such a fun little place to seek and explore. Was a bit worried about accidentally bumping into something expensive but everything was secured and their was room to navigate even in some tight areas. A must if you are visiting the DuPont DC area.

The Dupont Circle Citizens Association had our annual January "Resolutions" Party at the Mansion, as a Dessert and Champagne Celebration. The food, venue, and set-up were all fabulous. Many of our members enjoyed a tour of the Mansion, and loved it, even if they had been there before, there's always something new to explore.

Everything was perfect! I heard "the best meal I have EVER had" from several guests. It was so delicious and perfectly prepared. The Chef delighted us with his description of each course. Every one of the staff treated us like royalty! Our DC Chapter was founded at the Mansion on O and we all feel as though it is our home in the nation's capitol. Many thanks to H and Ted and all of those who have welcomed us time and again to the marvelous, magical Mansion on O!

The Mansion on O team was absolutely amazing to work with. Lady H and her amazing spirit and warm energy is felt throughout each interaction, from working with Madison as we planned the event, to working with the day of staff. Myself and my colleagues had a great time and many are already planning follow up visits with family and friends!
