My wife and I stayed at Shaun's during Labor Day weekend 2017. His place is clean, and comfortable, also personalized, not the kind of Airbnb that gets a bunch of IKEA furniture into a room. The area is calm and quiet, but public transportation is not that far away, I also saw some rental bicycle not far from Shaun's place, we were driving, and we always had more than one than one option to park, just a few meters from the house.
This room is in a second floor, which is just across the bathroom, the bed is very wide, and there is plenty of closet space. Shaun communicates quickly and was very helpful with his suggestions for places to visit, and mentioned Ethiopian food, which we tried thanks to his suggestion. From his place, the far end of the National Mall is at around 17 minutes driving, which is very good in a major city.
