the impression about habitation is normal. It has nothing to do with it, but in general it's okay. To the sea far without a car will be very difficult, but close to the central part of the city. take a car to rent a problem :) in general all ok. could not immediately deal with the dumping of garbage, the instructions were found only for 4 days of stay. and one more thing in Sicily will have to pay a tourist fee additionally. Sea, city and inhabitants of Avola are wonderful :))
