We chose Giueseppe's place as the first stop on a 3,5 week vacation around Sicily. We stayed here one week with our little son (9 months at the time), and it was a perfect base for exploring western Sicily and also for exploring Castellamare del Golfo. It is very close to the city center with its restaurants and bars, yet it is a away from the main streets in a quiet street.
The place is quite big with two large bedrooms and a well-equiped kitchen with enough room for a dinner table. Besides the roof terace (which is really, really nice!) the apartment has two balconies - one with sea view. One of the bedrooms also has a couch (not in the pictures), which we really appreciated.
Giuseppe lives in the same building himself and is always available for questions. The check-in and communications leading up to our stay went smoothly. Overall, we definitely recommend Giuseppes place and would love to come back.
