below is a link to another published website that gives some info regarding locations where apartment owners have been fined, see entry dated 17 November. I am not aware of any of these locations have been moved to Tourist status - maybe someone can clarify this.

I would think if you checked on the official tourist web sites for accommodation they would have the information for legal bookings. Try
