The place is as described, you will not find any bad surprises. Arabella obviously takes good care of the place, so everything is in good condition. The bedding is of good quality, including the sofa bed in the living room. The swimming pool is very good, with an incredible view. The stairs to the swimming pool work well, although I am not sure that an elderly person would be able to use it, or that they could hold a very heavy person.
The location is convenient, midway between Palermo and the Castellammare gulf beaches. Be aware that you will have to drive at least 20 minutes to reach pretty much any place of touristic interest. This was fine for us, but may be too isolated for some people. There are supermarkets close by with good quality products.
Arabella is a very good host. She made sure that we had everything we needed, including equipment for our young kids (again, of very good quality) and toys for indoors and for the swimming pool.
