Riccardo was very nice to meet us near the port, this was very nice, cause the weather was not so well the day we arrived and we were very tired.

He told us some interesting stories about the city, and gave us a small present when we checked in.

I must say that I think he is the best organized host I know. He has a common room, and the room with a computer where all the possible information that traveler needs is gathered:
bus routes, maps, booklets, even spare tickets for transport (so if you just arrived it's very helpful).
He has breakfast included which is super cool, so if you are on low budget this might help you a lot. He will also tell you all the possible cheap places and anything about the Catania or Sicily.
It was a bit cold the days we were visiting Catania, so he gave us a special warming device for bed.

You need to be very lucky to find host so generous and willing to help.
