We had a great time. Pierluca picked us up at the airport and was really nice. The view of the castle from the window is nice. It's close to the central market (which closes at 1) and to the Duomo. You can go everywhere walking. There are some restaurants just meters away.
Wifi, air conditioning and kitchen were great. The only bad thing was the first night we woke up 7.30 because there where men painting and working in the corridor and we didn't know about this beforehand (luckily it was only the first day).
There is a big bed at the mezzanine and a big sofa bed. (We were 3 but there is space for 4)
It was clean. There is everything you need: hairdryer, iron, washing machine.
I would definitively stay there again.
