I staid at Enrico's place with my parents for 3 nights. Enrico was super attentive in all the details, he even wait for us in the bus stop!
The apartment is exactly as in the pictures. Very spacious, clean, everything is new, and it has all what you could need. If you wish to cook, probably you will find what you need.
Regarding the location it's easily reachable by bus (the frequency of the bus is not so high), but if you like walking you can do it. We used to take a walk though the Trastevere to reach the center, it takes about 40 minutes. There's also a metro station not far away form the apartment, but we didn't take it.
Summarizing, we had great time at Enrico's place!
