We corresponded with Stephanie for this listing and she was great - very accommodating and was there to meet us and let us in to the apartment.
The apartment itself is somewhat bare, but we were just sleeping there so it worked fine for what we needed. It would have been nice if some of the owner's things were put away, but it was not a huge deal. Also, there were not many blankets available. The apartment was listed for 3 people and all that was provided for the air mattress were sheets. Since it was winter, it was chilly, and quite cold the first night without a blanket. Stephanie was very sweet, though, and brought us a blanket from her place for us to use the 2nd night.
You can walk to the yellow/green metro line relatively easily or it is a quick and easy Lyft ride to the busier parts of DC.
