Our family (including our 5 and 2 year old) stayed at Erin's DC home, and it was one of the best AirBnB experiences we have had. Really, this type of home is what is so valuable about AirBnB. 1) It really felt like we were living in Capitol Hill with short walking distances to grocery stores, restaurants, Union Station (just around the corner), and National Mall. 2) The playroom was just what our two young kids needed to start the day and chill in the evening. 3) The home is lovely with lots of amenities. It was like showing up to a fully stocked home, and all we needed to do was plan our adventures.
If you are traveling with family to DC and looking for a base for your family to tour around, this is the place to be.
