The apartment was exactly as described by Fabio and recommended by other guest. It is modern, spacious and clean. Everything a guest would want is within 100 metres of the front door. Supermarket, cafe's and restaurants.
Erice is a 5 minute drive out the road. Don't think you are missing out by not staying in Erice. The prices up there are double and for us at least it was "too" touristy. It's better to stay in Valderice and just spend a few hours up at Erice, then come back to the comfort of Fabio's apartment.
Highly recommended.
