We stayed for a week at Andrea's apartment, and we loved it. It is ideally located in Trastevere, just steps from several great restaurants and shops and very close to the river. The apartment is on the ground floor so there are no stairs to climb. It is very comfortable, with upscale furnishings. We visited in December and the central heating was appreciated. The bedroom has a King bed and is located in the back of the apartment, so it is very quiet.
At our request Andrea made arrangements for transportation to and from the airport. He met us at the apartment, he responded quickly to any questions we had concerning restaurants, etc. He was very responsive and helpful.
The only issue we had was the bathtub. While it might be great for baths we found it a problem taking showers. It was hard not to get water everywhere.
Besides that small issue. We completely in enjoyed our stay in Rome in Andrea's apartment.
