We had an amazing time (3 nights) at Antonio's appartment. We are Airbnb users for quite a long time now and we didn't often have such a warm welcome from an host. Antonio and his father are very nice persons, giving many information on the places to visit and eat at. They were very responsive to our questions and had many nice attention. They truly deserve their "super-host" tag.
The appartment is very clean and comfortable. It has all the necessary equipment to cook. It has a very nice patio and balcony. As stated in some other comments, we did hear a bit the close by ressort center, but it was not much and the music was not stopping very late. It was not a problem to sleep well.
We definitely recommend the place to visit western Sicilia. For information we visited from Agrigente to Erice while staying at this apartment. Selinunte antique site is unique.
