I recommend staying at Margherita's place. The apartment is bigger than the pictures, and it has everything you need. It is well kept and clean, and the view is insane. However, it does not have WiFi but that was not an issue for us... one remark, driving through Cammarata and getting to the apartment requires some nerves of steel... I guess that if you are not Italian, you might not be used to the tiny and windy streets that goes all over the city... we felt that we accomplished somthing that day after parking the car safe and sound. Lol
great experience and the place nicely set up.
