We went to Sicily in mid-October, a couple with 2 small kids (4 & 1) and This apartment was exactly what we needed.
Ernesto was very helpful even before we booked the apartment with answering our questions, and gave us every answer he could about whatever we needed.
the house itself is really great, it's old but amazingly renovated and styled with a real "home" feeling that is hard to explain before you come back to it after a long day of traveling.
the kitchen is great with some great surprises from the hosts and around the corner, you can find a wonderful bakery that the freshly baked smells that come from it will surely put a smile on your faces.
All in all, it a was great choice we made for our stay in Sicily and we highly recommend both the apartment and the hosts.
