We had a great stay at Stefano's apartment! It was very well located, close to the Vatican, a bit further from the city center but easily reachable by foot or public transportation.
The area is quiet and very safe. The apartment was well-equipped, very clean and spacious. It can be good to know that it's a bit below street level so there is less natural light, but since we were mostly outside, it was no problem. Moreover, the apartment is facing the inner courtyard of the building and not the street, so it's very quiet and safe. Wifi was a bit inconsistent but it worked out.
Stefano was very friendly and helpful, especially since we arrived earlier than planned. Communication was easy and efficient. Definitely recommended!
