Charles and his wife were kind and always answered our questions. She even helped my mom to park her car!
The room had all the necessary stuff for few days but I don't recommend it for a long stay. The neighborhood is SO FAR to be the best place in D.C.
My family and I didn't feel safe walking around and there wasn't any restaurant, nice park, or tourist place nearby. So we always had to drive or took the metro to go anywhere. Also, the TV connection was really bad on the second day.
If you only want a cheap clean room close to a metro station, this is the place. But I believe there are better places to stay and have a better experience of the city.
