We had a very nice stay at Paolo's Flat! It is very close to the center of Rome and Vatican so we were able to travel many distances by foot. Also Mario who gave us the key was very nice! The Flat itself is very spacious and suits everyone that likes unusual designs. So was good for us. Sadly neither the Dishwasher or the Whirlpool were working for us. But that's ok :).
Highly recommend using this place!
