Giacomo is a really great host. We especially enjoyed our trip with him to Etna where he takes you to some authentic Sicilian places to eat and drink and his recommendations for dining.
The view is incredible!
Although his english is basic (he mostly talks Italian), but we still made it work :)
Just a hint: you can't throw the toilet paper in the toilet (you have to put it in the bin), but that's the case in many places in Sicily.
Mille grazie, Giacomo!
