Room is small, but exactly as advertised. The room also had a small coffee bar and a large tv. The location is great as well - within walking distance to the Castro and right next to public transit. If you're looking to stay near the Castro, or Haight-Ashbury, I found this listing to be a bit cheaper than other AirBnbs in the area.
Would recommend earplugs. Noise travels easily through the apartment and I could hear TV noise until after midnight on both weeknights when I stayed. There was a fan in the room, which helped somewhat. But otherwise it's a solid place to stay, as indicated by the rest of the glowing reviews.
