Elena's place is exactly as described. Elena herself was perhaps the best Airbnb host I have had. Her communication was excellent. She provided clear directions to the house, lots of suggestions for things to do and her recommendations on eateries (restaurants, bakeries, and a takeaway place) were outstanding. I particularly recommend Nana's Bakery and the takeaway place in Castellmare! We were also welcomed with some Sicilian wine and biscuits. Thanks Elena!
If you are going for a week or more, then it might be useful to bear in mind that the nearest town and beach require a drive. However, the house itself is cool, comfortable and well equipped with everything you need to cook some meals there. It is also well located for the main autostrada that runs from Palermo to Trapani, so it is really easy to drive to all the main sites of historic and cultural interest from the house. So it can make a good base.
It is interesting to see an old Baglio in the midst of restoration, as there seems to be a lot of such restoration going on in Sicily. (Note, the house itself is restored with large, clean and modern bathrooms, but I don't think all the houses in the Baglio/around the inner courtyard are completed as there was some work being done while we were there.)
In summary, if you want a good base for a few days to explore the Western side of Sicily, this could be it. Elena couldn't be a better host!
