We have just returned from Lignano Sabbiadoro where we stayed at Hotel Daniele. It is situated near city center or in the city center, not so near the beach but you can always use their bycicles.
The room was verry simple but clean, the suprise was the breakfast buffet. There was everything and more, really great and they serve breakfast till 11 oclock.
The most attractive part of Lignano - e.g. for me - is unfortunatelly on the other side of big green park called Villaggio GETUR and that mean you have to drive there or walk some. There is all what you can think of, meaning shops, especially you need to look at some designer handbags and shoes.
Hardly wait to go there again....
