Paolo is a very nice and friendly person. To be honest I think he is the most helpful host of all I've met so far via airbnb :) Communication with him was really fast and nice. He gave me very exact tips how to get to the places I wanted to see in the area (including helpful maps :))
If its about the flat its modest but I think that if you are not very picky there is everything that you might need. The big plus is that the flat is situated close to the bus stop where you can take a bus for example to funivia to Erice that is close and worth seeing or to Palermo (about 2 hours by bus). The kitchen is shared so you have the opportunity to meet other people who are staying there at the time. I recommend Paolo's place ;)
