CAUTION. Spent 3 weeks in Italy and this is the only place I had issues with. The air con is non functional - on/off only with some (warmish) air. Open the window and hear the train that is right below. Host doesn’t speak English and was not flexible. We left 2 days early without refund. Even at the extra expense I could not stay in that room. It was the end of the trip and ruined an otherwise great holiday. Terrible experience. And don’t be fooled by the title Trastevere. That is the name of the building but it is not in that neighborhood.
