We had a great brief stay at Carla and Giuseppe’s place. There was just enough room for our family of 5. Our youngest loved the game room! There are outside stairs to access the unit, so pack light :).
The location is a little out of the way from the National Mall, but public transportation is easily accessible and there is lots to see between the house and the Mall—we loved driving by the National Cathedral, and all of the embassies! We would absolutely stay here again.
