Perfect distance from the Trastevere train station ... literally 3 or 4 minutes with luggage, but far enough away that you can't hear the trains.
Gianmarco was great with communication, he gave pointers on what to do in Rome and how to get there, and made sure we knew how everything worked in the apartment before he left.
Nicely laid out apartment. Clean, air-conditioned, comfortable.
Great place to stay for a tour of Rome!
