Biagio's apartment was a good choice for us: it's pretty spacious, clean and we had everything we needed. Communication with Francesca, Biagio's daughter went very well and she helped us with all questions we had. We could also check in earlier.
There are two supermarkets (Todis, Conad) and one chemist (Acqua & Sapone) near the flat. You need approx. 20 minutes by public transport to the city centre (there is a metro station of C line in a short walking distance and you can get to Termini train station thanks direct tram lines 5 and 14).
Pigneto is a suprisingly district! During the day seems to be a place where Rome's inhabitants live their quiet live. In the evening many nice bars and restaurants nearby open. We tried one of them – Necci dal 1924 – and were very satisfied :)
