This used to be just about the cheapest marina in the Mediterranean, it used to be local council run. Now it has been privatised and is owned by PortodelleGrazie.

Their lat/long info is slightly different from this website, on their business card it is 38deg19',52N-16deg25',84E
Unfortunately most of the website is in italian. But if you call the office there is a very good english speaking friendly receptionist for information.... I hope this is helpful as there is not a lot of info on this marina on the internet. Safe sailing...
