The location of this apartment is excellent - especially if you're looking to escape the touristy areas and stay in a real Roman neighbourhood. There are loads of nice restaurants and coffee bars nearby, and an absolutely incredible gelataria! The apartment is only 10 minutes walk from the main train and bus station as well.
Frank was a great host and replied promptly to any queries we made before we arrived, he also let us know about good areas to visit with a handy map on arrival.
The only thing that I would say that wasn't so great is that the apartment has no curtains! And there is a fairly big window that looks into a courtyard and lots of other apartments, so we felt privacy was a bit lacking!
