I'm in DC often, and have seen my fair share of average AirBnB's here. This one is perfect! Large, warm, very stylish with everything you need. Right by Dupont Circle, so very close to everything. The owner is lovely, responsive, and helpful. Couldn't fault it at all - I'm looking forward to staying here again!
(Note: you'll need cash for the laundry card. And get coffee from Emissary!)
