We enjoyed our stay at Ilaria's apartment.
The neighbourhood is great, plenty going on, while the flat itself is quiet, large, and well set up (although the washing machine was out of order when we were there, you might want to check that that has been fixed before booking).
Ilaria was easy to communicate with and checking in and out was very straight forward.
I would strongly recommend Ilarias apartment. it is walking distance to the major tourist attractions and there are plenty of buses and trams for those who don't feel like a stroll.
