Very nice apartment. Very clean and organized. Location was not in the middle of the city but in a leaving neighborhood called Pigneto. Public transportation was very good (metro, tram and bus stations all less than 5 minutes walk from the apartment) which allowed us to get from the apartment to pretty much all the historic attractions in approx half an hour.
Around the apartment are many restaurants, cafes and bars which all close late (not before midnight).
All thing was that when we arrived we asked Roberto about the hot tub and he told us it was broken but did not tell us before booking or arriving.
All in all the apartment was great and Roberto was a very helpful host (was flexible with check out time).
