I cannot recommend this stay highly enough. Despite it being in a basement, it doesn't feel too tight, at least for two people. There is a large, well-appointed kitchen, and the bedroom is a good size, as well. The TV in the living room has cable, and there was a Netflix app that I logged into during the stay, making winding down at night feel very homey. The bathroom is absolutely pristine, and my fiance rated it as his best ever AirBnB shower (size, cleanliness, water pressure, temperature, and shower head height were all perfect). The bed isn't too hard or too soft, and had a little spring to it. There is a washer and dryer in the bedroom, which is a nice convenience for longer stays.
Perhaps the best thing about this stay was the location. There are restaurants and coffee shops within walking distance, and tons of others a short drive or Uber away. There were also bikes and scooters for rent nearby, we just didn't break into that world as our stay was short. We were not far from the National Mall, which was about all we could do given COVID restrictions, although I think it would have been easy to get to all of the museums that DC has to offer had the been open.
I would absolutely stay here again. My only regret is that I didn't have x-ray vision to see into all of the beautiful homes in the neighborhood, and I couldn't try every amazing restaurant in DC.
