I think it was my best ever airbnb experience. Great host who was super attentive and always willing to help with sightseeing tips, taxi and everything else. Piergiorgio lives right across the hallway on the same floor which was very convenient if you need any sort of help.
Spacious huge apartment with everything you will need during your stay and even more.
Located 10 mins by walk from Vatican, but in non-touristic very quiet residential area where Italians only hang out. Lovely true Italian restaurants nearby, 24/7 big supermarket is just 5 mins by walk from the apartment. Metro is 10 mins by walk and bus which goes directly to the city center stops right in front of the apartment building.
Someone may say that the area is not within walking distance to the downtown, but with public transport network it was not an issue at all. And I honestly find it as an advantage - I enjoyed living in this quiet residential area.
