This place is mostly occupied by college students, so expect an according level of cleanliness. My room was fine because fortunately I had a pretty clean roommate, but the bathroom (shared with others on my floor) was kind of a mess. In addition, the A/C unit in my room was pretty loud - I'm a deep sleeper so it didn't bother me, but that's something to keep in mind if you are a light sleeper.
I will say that the location is super convenient - just a few minutes' walk away from a subway station and a grocery store. In addition, the host was very responsive to my messages and gave clear instructions for an easy check-in. The staff that I interacted with were pretty nice. If you are looking for a cheap stay in downtown DC, this is one of the few options. If you're not too picky about cleanliness, then it may be a good choice. I'm just a clean freak, so I don't think I would stay here again.
