Paolo was a great host! My room was in the back corner next to the bigger bathroom. It was kind of dark. I would recommend this location as a starting point for your search for a long term apartment.
For just a host term stay in Rome it is too far away from he city center and for long term (as I did) it is too dark and kind of hard to establish a cleaning system for the common areas, as people are constantly moving in and out.
Anyway Paolo is a great host!
