3M's experience with The Mansion on O Street was outstanding, beginning with the personalized attention we got throughout the planning process and ending with the execution of an extraordinary private event. Our guests were thrilled to visit a place that was not a common destination for most DC tourists, and even with such great anticipation, their expectations were far exceeded. Thanks to the world-class staff for making this a truly memorable experience.

Such a fun time exploring all of the fun rooms! The intro was helpful and we found several doors! Highly recommend as a fun thing to do especially on a rainy cold day like today.

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!
