Cristiano's place was cozy and clean indeed and he was very welcoming, considerate and generous. The location of the place is just between Bologna station and Tiburtina station such that you could take a subway easily at either of them as you want. Also, there is a bus station where to take a bus to the center and Vatican city just in front of the place. Only one demerit that I can find is the room is not well soundproof. However, neighbors are silent at late night and I think it's a kind of common things for the old flats in Rome.
