We had a great stay at Lorenzo's place. The room was very spacious and the bathroom was clean, which is exactly what we were looking for.
Even though it's a shared apartment, there were no noises from the other guests, except for the moments when they locked/unlocked the doors, which is not very disturbing.
And finally, Lorenzo is very friendly and ready to help at all times. He had recommended us some exceptionally good places to eat, for which I can't thank him enough.
As a general note, the apartment it's situated at 5min walk to Lepanto metro station, 15min walk to the Vatican and 30min walk to the city centre and there is a mini market across the street.
10/10 would recommend
