Needed an affordable place to stay with easy access to the red-line. This was a ten-minute walk from the metro, in a great area. The place is located close to several embassies, apartment buildings, very nice houses, and a small assortment of restaurants to get you buy if you don't want to go to other areas of DC. There was little to no road noise so that is not an issue. The radiator, at least that is what I think it is, located in the bathroom along the bedroom wall, was a little loud for me at night, but it could be just because I"m a light sleeper. You will hear the neighbors through the walls but only during "normal" hours so that was no problem. I was there from Sunday through Friday.

The apartment is essentially at the top of a hill. If you are carrying multiple bags the front steps could be tricky, but there is a way to get to the apartment from the back, so ask about that.
The place is comfortable and in good condition. There is no TV, so if you expect to watch TV bring a laptop or iPad and stream movies instead. The internet is very fast, and I had no problems with it. All of the furniture is a little low for me, I'm 6' 3", so it was difficult getting up and down from the couch. However, the arrangements are very comfortable, including a nice kitchen area.
