First time using Airbnb, was super glad this was my first experience. Place had the basic amenities(towels, soap, extra pillows and blankets, coffee). Plus metro cards, so you don't have to buy one, and grocery cards, for discounts at the local store that is right around the block. When something broke, maintenance was quick to fix it.
Only issue I can see is the free parking, if you are expecting to use it. The spot looks like it can be used by either the top or the bottom renters. I should point out, I had a change of plans and didn't need the spot while I was there. So I had no reason to bring up the topic during my stay.
Other than that, I would recommend this place and will book again next time I visit DC
