I spent a week in this house in july 2017, and it was great!
The house was exactly as advertised, very luxurious and roomy.
The entire ground floor of the house and the garden / pool area pictured was for the exclusive use for us.
The host family were incredibly kind and hospitable. As an example, as we arrived late on the day of the check-in the supermarket down the street was already closed, so the host had prepared some light dinner for us and supplied some breakfast, so we would have something to eat in the morning.
The host family lived on the first floor during our stay, but with a separate entrance, so we did not bother each other.
If I visit Sicily anytime soon, I would definitely stay in this house - 10/10!
