Our stay in Carlo's apartement was very nice. My boyfriend and me enjoyed it very much for a few different reasons:
The apartement is very nice furnished, very clean and equipped good. We loved the small balcony and enjoyed sitting there with a cafe and watching the people walking down the small streets. The location is perfect, it is quiet but also close to the centre in 5-10minutes walking distance, where you can find a lot of very nice and good restaurants and some shops. Castallamare is also a good point to make some daytrips to the nature reserve Zingaro, San Vito lo Copa, Erice or also Palermo.
The communication with Carlo was also good. A friend of him picked us up from the street, welcomed us and showed us the flat - very kind. We were happy about some supergood sicilian cookies and a bottle of wine, water and icetea in our refrigerator. His friend and mom were very nice and helpful all the time.
So we can just highly recommend this apartement and will go there again, when we come to Sicilian next time.
