PROS: Good free parking outside or max 20 metres from gate. Private and secluded. Quiet. Good kitchen with lots of basics already there (olive oil, mineral water, tea, coffee, butter etc etc. Aircon works well. Wonderful view as far as Capo Passero Island. Corrado helpful and available. Highly recommended. Small shops mini-supermarket and bakers within 200 metres.
CONS: None regarding the flat. But my most important tip about travelling to Sicily is DON'T RENT CAR FROM SICILY BY CAR.
