Paolo was the consummate host. We couldn't figure out how the medieval style key worked and we were essentially locked out. He came at 9 PM in about 10 minutes and showed us how the door worked. It was easy -- we were just being silly.
The space is pretty large and the bed is very big. Plenty of living space and a balcony.
Location is right next to viale di Trastevere and the 8 tram.
We would stay again !
