I enjoyed my stay in Rome including the apartment that I rented - it was cozy and clean. The place is very close to Vatican and within a walkable distance for a lot of the main destinations in the city. It was fairly quiet during the weekend, but the street does start buzzing on workdays.
A few things to keep in mind though. First of all, be sure to inform the host when exactly you will be arriving, I only gave an approximation and ended up waiting half an hour at the gates for the host to arrive and check us in. Secondly, the walls are very thin. We could hear the neighbors walking and talking (and they weren't even talking loudly), and they could probably hear us too. The shower didn't have a shampoo or a body wash, the only toiletries provided were two bars of soap. The shower head sometimes got a bit leaky which was very annoying when it happened at night, as the water just hit the floor from a great hight.
Overall, a nice place, but not without issues.
