I stayed here for a family trip to DC with two kids ages 6-10. The stay was fine, but I felt the overall quality was not close to that of the listing photos. The house is very old and there isn't a level surface (floor, stairs, ceiling) to speak of. This would be fine, but the other appointments in the space were lacking or altogether bad. The kitchen in particular seemed like a utility room that just happened to have a fridge and oven. Very poor layout throughout and overall disappointing.
That being said, the unit was very clean and had a great location. It would be a great stay for college kids visiting DC.
