Thanks for taking a good look, I guess it could be the location, but I honestly remember a smaller island, on a lake, with a hotel on it in the photograph. Maybe it was from a different angle? After all how many lakes in Italy have hotels in them?

Thanks again for trying.

My runner up is the islet of San Giovanni on the same lake: http://static.panoramio.com/photos/large/122043835.jpg (which is also mentioned in http://www.davinotti.com/index.php?option=com_content&task=v...). In reality it was probably an amalgamate of several reference locations.

This is it! Thank you =]

You are probably talking about lake bled in Slovenia https://upload.wikimedia.org/wikipedia/commons/8/84/Lake_Ble...

or lake skader in Montenegro.
