As far as I could tell, this isn't a room in a home; it's an Airbnb hotel (maybe a hostel where everyone gets their own room is a better description) with 6+ rooms rented out on a constant basis. Expect to have lots of tourists coming and going all day and night. This wasn't a big problem for me, but I do wish the description had been clearer in explaining what the deal was.
Location is OK. You're not in the U Street or Adams Morgan neighborhoods (the closest lively neighborhoods), but you can walk to them. Metro is close. Some areas around the house can be a little sketchy at night -- not "you're taking your life in your hands by going outside" sketchy, but just "you need to pay attention to your surroundings" sketchy.
To operate the front door you have to download an app called August that basically wants to collect every bit of personal information about you (why does it need to go through my photos, for example, if its job is just to open and close the lock?). I can see how technology like this is useful for a situation like this, but I wished I could have gone in and out without having to add more untrusted software to my phone (and I would worry about what could happen if you had a technical problem getting in or out, because although the host was very communicative, it didn't seem like anyone was on the premises to help you if you had a problem). All of the individual bedrooms also have locks with keycodes. Remember your keycode so you don't lock yourself out of your room!
The place was very clean and although the furnishings are basic, they are modern and well maintained.
Bottom line: This wasn't a good fit for me because it felt like a weird hybrid between a hotel and a traditional Airbnb. But I could see it working well for people who want low-cost lodging for D.C. and don't care about the lack of hominess, the lock situation, etc.
