We had a perfect stay. The location is very fine and Allessandro is a very nice host.
Only thing we had some trouble with was the warmth. Airconditioning is available, but does its work only for the down floor. Upperfloor was a bit warmer. However, it was Rome and 34+ degrees, so it was relative cool in our appartment.
Still, I rate this AirBnb 4/5, because everything else was very nice.
