We stayed in other two big cities with AirBnB and this host was by far the best one for a couple of reasons:
1. Italians are very friendly
2. He welcome us very well and the flat is great. Gave us a tour and recommended us a few things to do
3. Was available over text and whatsapp perfectly
4. Arrange to leave our bags guarded for a few hours on our last day.

The place is much better than the pictures and is located in the best place.
Very comfortable.
