The apartment is in a lovely part of the city, right next to a subway station and really well equipped. It's a basement apartment, so the ceilings are a bit low and the light a bit limited, but otherwise it's perfect: really comfortable, super clean and certainly big enough for 1-4 people. The kitchen is especially nice and really spacious.
The location is perfect: it's right on the blue/orange/silver line so it's 10-20 minutes from all the major stuff downtown. The neighborhood is really pretty, with tons of old DC-style townhouses, coffee shops and grocery stores, and open space.
