We loved our stay at the house of Marinella and Davide. The flat is lovely furnitured and located just a few minutes walk to the beach. Compared to other beaches in Sicily this beach is really nice and not crowded. To the center of Avola it's a 20 minute walk. Avola itself isn't a Must-See so we recommend having a car to go to Siracusa and/or Noto for Sight Seeing.
Marinella and Davide are great hosts - always there when needed but really unobstrusive so we took the flat to our hearts like a home. Best is the garden which can be used even for barbecue. You shuold only remember to bring basics for cooking (salt, oil, etc.). Towels, dinnerware and pots are sufficiently available.
