We enjoyed our stay at Francecso's flat in Catania. The location is good (around 15 minutes walking to the center and nearby to supermarkets) and if you are travelling by car, you will definitely get a parking space. Although the neighborhood is not the prettiest, it is a good venue for reaching the autostrada if you are interested in doing some daytrips.
Communication with Francesco was good. But for future guests it would be important to know that in Italy there is a new law that requires guests to provide a copy of the passport to the hosts. We did not know that in advance and I was quite surprised.
On other things, the amenities at the flat were quite good. We had everything we needed, but the bathroom had a terrible smell.
Personally, I did not like very much the interaction with the woman (Teresa) that gave us the keys: she was a bit of a gossiper, always wanting to know where were we going, at what time we would be arriving, etc. Since the first day of our stay, I did not liked very much her attitude, she was a bit rude when showing the apartment, giving us orders instead of explaining how things worked.
Besides that, everything went ok.
