The flat is closed to the bus lines so it's practical to visit the city. furthemore, Trastevere is really a great place so the flat is well places. Finally our correspondant for the flat was really nice
But the flat (the bedroom) is just over a restaurant it was for us really noisy ...it was the bad point about the flat. At night we wanted to open the window because it was really hot (we went to Rome in July) but we couldn't because of the noise.
