The apartment is indeed clean, quiet and handy. It is around the corner of Santa Maria Maggiore, 5 mins walking from Termini train station and at a crossroad of Metro A, Metro B and several bus lines + walking distance from neighbourhood Monti,Vittorio/San Giovanni or San Lorenzo. However we were a bit disappointed as it was a bit dark (the flat is at mezzanine with windows on the backyard) and as the bedroom is at the entrance door (pictures showed it but we did not realise). Nicely furnished and renovated with a very big shower. Communication was very easy with Fabio.
All in all a positive experience.
