Marco and Gabi were very welcoming the moment I stepped into the hostel. They make you feel at home immediately and are always trying to come up with new ideas to make your stay memorable. For example, they organise ping pong night the day I was there and I heard they have other activities like sunset seafood party on a boat and acro yoga sessions. If you want to have fun (not just pure drunkedness as in many other hostels), this is the place to be.
There's A/C, fully-equipped kitchen and many commons areas to hang out. Wifi is good as well as water/hot water supply. The only downside about this place is that it is 15-20 minutes walk from the city centre/beach. It is quite isolated from the other things in San Vito Lo Capo but you should be able to get used to it after some time.
