Jessica's place was outstanding. Check-in was very smooth and the location could not be better. Only fifteen minutes from the airport, and twenty minutes to the national mall. The neighborhood seems to be mostly locals, and it is very close to the Navy Yard so I felt safe most of the time. The price is much cheaper than getting a surrounding hotel room, and it has better amenities.
The room itself was quiet and had everything I needed. Extra towels, utensils, and a full kitchen made my experience even better as I could save some money by visiting the local grocery for organic produce. The bike share system in front of the property, and the subway close by it made it even better as I could travel to anywhere in DC without worrying about how I would get back.
I didn't have any problems with the neighbors, nor did I ever feel unsafe in a new neighborhood. In one word: Homey.
