This is a very good apartment in a part of Rome which is away from the main tourist areas, but there are good public transport links (metro, tram, bus) within two minutes walk. The area has useful local shops, bars, and restaurants, most of which stay open quite late.
The apartment can be accessed from the Via Tasso, a quiet backstreet, or from the main road (Via Emanuele Filiberto) via a quiet tree-shaded courtyard. Apart from during the day, when the local school is open, the apartment is very quiet.
The apartment has three spacious bedrooms and living room. One bathroom is a good size, but the other is quite small. The showers were very good and the hot water was...hot! The kitchen is a "galley" kitchen, but you're hardly going to be cooking vast meals when there are so many great restaurants in Rome. Towels are provided and the bath towels are a good size compared to some hotels. A few more tea towels would have been useful. Everything was very clean. The apartment is on the first floor but there is a small lift.
Communication with Pier Paolo was excellent, and a couple of days before we arrived Claudia contacted me to say that she would check us in. Claudia was extremely helpful during check in and showed us where everything was kept. She also gave us a map and suggested places to eat. I needed to contact her a couple of times during our stay but each time my questions were answered efficiently.
I would certainly stay in this apartment again, and I would recommend it to others.
