The only mistake we made, if mistake it was, was coming here in late July, with temperatures reaching 35 degrees Celsius in the daytime. But then, what could be nicer that enjoying the cool inside the antiques-studded house or slowly roaming the large garden, picking up figs and tomatoes? Plus, the beach is just an easy downhill walk away. (Uphill is a different matter in the heat.) There also is a pool you can use for a small fee in the holiday colony next door.
In short, we'd highly recommend staying in this Casolare. The house and the garden are beautiful, the view is superb, it's a very quiet location. Bring lots of mosquito repellant, though!
Luca and his parents were super-helpful. Luca would frequently message us with sightseeing or practical suggestions, and he was always reachable. One afternoon, a defect in the water pump blew the electrical fuse. After a quick WhatsApp message to Luca, we quickly had Luca's father and two handymen on the grounds to fix the problem.
Balestrate town is small, not particularly special, but likeable and not too crowded. There may be more sights in other areas of Sicily, but Palermo, Trapani, Erice, Segesta etc. are short drives away and will keep you occupied for quite some time.
