Maria is very friendly and helpful. When I arrived, she picked me up at Via Bonelli station, and when I left, she drove me to Trastevere. That's great help! I had a nice time at her place, and a nice visit in Rome.
Her place is in a quite neighborhood, 2 min walk to the bus station. Bus 719 is quite frequent, and it can take you to Trastevere, Piramide. From Trastevere, you can take trains or tram 8 , to many tourist places such as Piazza Venezia. From Piramide, you can take metro or tram 3.
