Greeted at entrance to village by Graziano's father, who also arranged the parking permit for our car, residents only are permitted vehicles in to the town. Accompanied us back to the apartment and showed us the facilities, washing machine et cetera.
The apartment is exactly as described and shown in the pictures. Very quite in the evening, lovely balcony to enjoy breakfast on. Castelmola is a small beautiful place to walk about, quite steep and enjoyable for a day or two in itself.
A number of buses visit during the day, there are four restaurants serving in the square near the church. We ate at the Il Vicolo restaurant which was very good. (not in the square, but passed on way to apartment)
Also, took a trip out to Naxos, which is a 30 minute drive although only a couple of kilometers in a straight line. (Twisting mountain roads, which you obviously know about if considering Sicilia)

All in an excellent trip and would certainly stay at this residence again.
