Domenico was very accommodating, he even brought me keys the night before at the place I was staying because he was leaving town the next day. The place itself is very spacious and close to everything you might want in Trastevere. It has nice light as well. The noise from the street was not an issue for me even though I am a light sleeper (it was raining and the windows were closed at night and I had ear plugs). As another reviewer said, the noise from the next apartment can be a bit of an issue if the guests are loud, but Domenico immediately asked the family staying there to be quieter when I asked him (they didn't speak English, nor I Italian, so I couldn't communicate directly) and that solved the problem. He is a super responsive host, and I would stay there again.
