The house was super clean and and very well equipped. Almost everything you wanted was there. Couple of things for improvement would be (1) a toaster for the kitchen (other than that the best equipped house I have ever stayed in) - and (2) aircon in all rooms rather than just in the kitchen could be useful. That wasn't a problem for us as we were visiting in late September but I imagine in the hight of summer it would be very stuffy - particulary in the twin bedded room that has no window. (though there was a fan supplied to circulate air. WE actually put the air conditioning on in the night (on low) and left the. bedroom doors open and the conditioning chilled the whole house. Off course leaving all the bedroom doors open may not be suitable for everyone. (3), a facility like google cast or smart TV to watch Netflix or a hdmi cable to hook lap top up to the TV as TV only had Italian TV.
These are minor things but just mentioning them as if addressed Giovanni's house would be the perfect escape.
Giovanni was also very polite and welcoming and I would highly recommend a stay here. Perfect location for beach and to visit the Archeological park at Selinunte.
