The stay at Viola's apartment was really nice! The house is lovely and you can find anything you need plus a cute little cat. Although he's quite present in your room, you will not be disturbed, because he knows how to behave. The neighbourhood is a real secret hint. It is quiet, but also has plenty of bars and restaurants nearby.
I felt very welcomed by Viola who was always ready for a chat and giving recommendations about Rome. I'd definitely come back to visit her and Rufus!
