You can not find a better spot in Rome, not too far from the Vatican, a few minutes to Piazza Navonna across the bridge, close to a supermarket and a place to print tickets.
The appartment is clean and the bed is big ;).
Lorenzo knows some good restaurants (Caccio e Pepe and La Dispensa Dei Mellini) and it was worth it.
I would recommand this place to my friends if they go to Rome.
