Camped here for a few days in August 2013 and with the intention of going to Tremiti for 1 day. The campground was more than adequate - but we couldn't park our car near the tent which was a bit annoying. The shower facilities weren't too great (cold water showers only) but they were ok for just a day or so - lucky we were there in summer!
The best part was the restaurant - amazing pizza! And really cheap. The pasta could have been better as we'd already been spoiled by the pizza the previous night.
The only main downside was the loud train directly behind the camping area which went past regularly at night, but only once or so per hour. And there was loud party music from the bar area.
