We stayed for one month at Marco's place. Overall, we had a wonderful time. The place is beautiful, comfortable and well equipped. We loved the outdoor kitchen! Most importantly, the villa has a stunning view over the bay. It is close to two beaches (a sandy and a rocky one). Capo Zafferano is a nice place to stay, but truth be told, it is quite residential and we spent most of the time exploring other areas. On weekends, music is blasting from the boats down in the bay at highest volumes, so if you are not ready to rock it out, plan to be elsewhere during the day.
Two things slightly bothered us about our stay:
-- Finding the place and getting in was difficult since we did not have internet on our phones. There is no street address on airbnb and no instructions were given initially, although Nino, our point of contact, tried his best to help.
-- The electricity bill at the end of the stay: Although we were alerted that we had to pay extra for electricity, we did not expect that we would be charged EUR 50 per week, having not even used air conditioning.
In all, a very nice if highly priced rental.
