I don't know if it's seasonal -- I was there in late May, and in addition to eating at the restaurant in the grotto, I stayed at the adjacent hotel, which was reasonably priced and had views right out over the sea that felt like being on a boat. There were, however, a lot of steps to get down to the restaurant level, and I have pretty awful knees. It was worth it, but I'd be lying if I said it was a walk in the park. More of a hobbe.
