Sergio was very accomodating and a flexible host. We travelled with two small children and Sergio arranged for a baby crib and chair upon request. The apartment was very conveniently located, and great as a base for exploring the majority of Cefalu and its beaches. The apartment was well equipped and we did not lack anything during our stay. The garbage system was a bit cumbersome (need to carry it ~10 mins away), but I assume this is a result of the garbage system in the town itself, and it's not a major issue.
Cefalu itself is a great place and we'd love to be back!
