I spent a beautiful week in Rome with my parents. Cristina was very very kind. She gave us a transfer from the airport and back for a decent price and when arrived to the flat she shown us the neighborhood and even helped us to buy a weekly ticket.
The flat is small but nice and the bus 170 stops right at the corner. There are many shops nearby. But on the other hand if you take the bus to Termini it's extremely crowded and can be very very slow (45 minutes). On the other way by bus 170 you can reach the metro and it is much more faster but getting to Termini is still about half an hour.
