Kamila's little house was great for our week-long stay in DC (my wife and I, first time in DC). First, the area is really incredible, a couple of blocks from the metro station (there are two entrances for the U-Street station). The area is very walkable at any time of the day/night and things are closer than they seem on the map. It's pretty easy to walk to Adams Morgan and back. The neighborhood is full of life and great places to eat and drink, yet the block where the house is located is extremely quiet. We also didn't have issues getting buses on U-Street to reach places the metro wouldn't go (like Union Market).
The house was spotless clean and everything inside it felt like new. The shower was great, and it has a glass door. Good kitchen appliances. Washer/Dried worked perfectly. We had breakfast on the back everyday and it was very pleasant. A/C was good, with Nest Thermostat.
The house is pretty tiny. Not an issue, but it's smaller than it looks on pictures. We thought it was fun. Kamila was always reachable. Check-in and check-out were a breeze. Loved not having to worry about keys.
Two things to know, not dealbreakers: one of the beds is comfortable, but a bit on the softer side. There's a second bedroom, but we didn't try the bed. One the main bedroom the shades aren't blackout, so it gets a bit bright in the morning. Bring an eye mask if that's something that bothers you.
To sum up: location, charm, cleanness.
