Luca is very welcoming and very easy to communicate with. He provided a very helpful list of information about visits, restaurants, ...
The location of Luca's flat is perfect to visit Roma by walk: at the center of everything! 5 minutes from piazza Navona, 20 minutes from the Vatican, ...
The appartment itself is nice: really clean, tidy and confortable. The living room is a bit noisy if someone has to sleep there (earplugs should do the trick), but as we were a couple and as the room is at the opposite of the street, we had great calm nights after full days of visiting.
I will definitely come back to Luca's appartment when coming back to Roma (so much to do and visit!).
