The five cabins of the hotel are each perched on branches and reinforced with giant stilts, offering a bird's eye view of the lush forest on the Polish frontier. The houses are capable of housing up to four people, with prices for the smallest of the houses starting at 160 euros (191 dollars) including breakfast.(AFP/DDP/File/Norbert Millauer)
