We enjoyed our stay at "Casa di Margherita". It was clean and we were surprised by small items the host left there when we arrived. Even if you need a car to reach the next beach you have access to the sea via small staircases. It was a pleasure to dive along the kliffs.
You should definitley rent a car to reach other places like Siracusa or Catania. Cause the streets are not really made for nice walks.
All in all: We can definitley recommend this apartement.
