We spent a stay in Valerio´s apartment and it was really great.
The apartment is very nice, clean, huge and bright. There is a tram station just on the main door, so you can reach the center easily.
Neighborhood is very nice too.
Valerio was not available these days but a friend of him received us and was really kind. In fact, we agreed a late check-in because of the flights, and there was no problem at all. Besides, Valerio responded very quickly to the email in case we had some doubts.
To sum up, an apartment to repeat.
