We've been visiting San Vito in 2nd week of June. Two adults and two small kids. The apartment itself has very good localization, it's like 3 mins to the beach. It's close to supermarket, there are many places where you can buy sicilan goodies. And what is probably the most important it's 3 mins from "Pizza E Sfizi" that serves best pizzas I've eaten in San Vito.
Giampiero and his wife are very helpful and kind hosts. We arrived in Savito late in the evening and there was no problem with accommodation. Also on the day when we were living they helped us with storaging our luggage so we were able to spend few more hours on the beach.
Communication was very good.
I recommend this apartment, you will not regret.
