Lovely house and great location. Joseph was very accommodating and did his best to please and see to any requests. For the winter this is a perfect house as it has radiators heating in every room which is rare in Siicily - though the timings for the heating could be extended slightly.
Out only complaints would be the Pizza joint underneath the apartment which is quite noisy in the evenings - at weekends till 1am though in the week it is closing early by 10am). We visited in winter month of Jan so it was probably quieter than it may be in the summer - those wanting a quieter life or want to sleep early may want to take that into consideration as loud voices echo around every room in the house. But thanks to the Joseph (Giuseppe) who asked the pizza owner to quieten it down for us - which worked. Also the fact that we had no internet which was somewhat annoying as we specifically asked the owners to check that the internet was working as we had to do some online work during our stay, Unfortunately the antenna was apparently damaged during a storm and was not fixed in time for out visit, We have to buy an add on from our UK phone supplier to be able to do the work and to watch netflix which was and expensive add on - and as one knows, we are now limited to 12GB per month due to Brexit business.
Apart from those two things the house was pretty much perfect.
Custonaci is a nice real Sicilian town and is perfect or exploring the Monte Cofano and Zingaro Nature Reserves and also to visit Erice - which is highly recommended.
