Fausto was friendly host, spoke English well, familiarized with the apartment and neighborhood. During the stay he reacted to our questions and request really fast.
The description was accurate, actually the apartment was bigger than I imagined - more than enough space for us, but, of course, we were only two. It also had extra amenities like speakers to play music from the phone or grill (that we didn't find time to use).
Neighborhood was nice and quiet. With a car we could reach center of Monreale in ~5 minutes, Palermo also very close.
All in all, it was a steal for the price we got.
