Very nice option to stay in Avola. Close to the town center.
I’d say the having some vehicle in disposal is the must while staying in Avola - almost nobody walking, usually people use motoscooter or car even for short trip ( e.g. to the beach).
Walking toward the beach is a very challenging in hot months (July, August) because the return trip is uphill and 1,5-2 km could exhaust you heavily.
So it is better to consider either to walk back earlier than 11 AM or to rent a car/moto/bike.
Marzia offers bike rental.
During our stay once there was an 4 hours electricity failure in the whole building (during night time).
So the fridge had been off and our food went bad.
As a compensation, Marzia offered us a free rent a bike.
While sleeping upstairs one can be stuffy (even with conditioner on), so we slept on the couch downstairs.
Generally the apartment is very good, in my opinion the price/quality ratio is excellent for Sicily.
