Paola's apartment was perfectly located--a pretty street, a short walk to market, cafes, tabachi, and an easy trip by tram across the river to the city center. The Gianiculo hill with its giant park is located just up a flight of stairs at the end of the street, and we loved exploring that, too.
The apartment itself is bright, with high ceilings, and fit four of us (adults) just fine. It was clean and well equipped.
We never did meet Paola, but she'd arranged for an assistant to let us in, and later her nephew Stefano, whose English is very good, checked on us to make sure all was well. It was!
