Actually, it is quite a decent stay for this value (you'll have no kitchen, only microwave and coffee machine, and also, you'll hear the child who live upstairs well, but this is not real problem). There were no problems with cleanness or host, communication was OK.
However, the neighborhood is not good at all. Actually, Anacostia is mentioned as one of the most dangerous areas in DC and it is easy to see that things are not OK when you walk to the subway station or to the nearby market.
So, if you know what to expect from the southeast of DC and ready for it, this can be quite a good option. We were not ready.
