My wife and I spent five days In Rome. Domenico met us at his apartment as we arrived from the airport and was very kind and helpful. During our stay he was very responsive whenever we needed him.
The apartment itself is lovely, very nicely decorated and just the right size. It is located in a very lively area and in the late evening it can be quite noisy, but that's the whole idea of staying in Trastevere. Just below the apartment there's a great bakery where you can get great bread and pizza. It is close to main attractions such as the Colosseum and the Vatican. The only thing we missed in Domenico's apartment was some more kitchen utensils, such as a cutting board and a good knife.
Surely a great place to stay in in this lovely city!
