This is a great and charming place to stay in Trastevere. As the other reviewers have found it is noisy at night - no way not to mention it! - but with the windows fully closed the noise is basically blocked out. There is a good fan that can be used to air the room a little too.
We enjoyed the prosecco that was left for us before heading out for the evening, and despite the buzz outside, this AirBnb feels like a little oasis of calm. Bed comfortable, shower powerful & hot.
