Matteo was a great host, he always responded very quickly when we had questions, he even looked up bus schedules for us before the trip and he regularly asked if we need anything which was very kind. When we arrived he gave us Sicilian sweets and a bottle of wine which were delicious. The flat is in a great location, there are nice restaurants nearby and getting to Mondello beach and other cities is quite easy by buses from there (e.g. to Cefalù and Trapani). The flat is well equipped, we had everything we needed in the kitchen for cooking. There are sunshade umbrellas in the flat, which is very useful if you go to the beach, we always brought one with us. The only downside for the flat that it's on the ground floor and the window is faced to the street, but the street is quite peaceful and empty so it was not really a problem. Overall I can recommend Matteo's place, we enjoyed staying there.
Note that if you want a great adventure, be sure to visit Favignana island and rent a bike there.
