Why not try staying in a tree house? This unusual place to stay is perfect for nature lovers who like to runaway from civilization. Houses are builded around the trunk so living tree is placed in the centre of the hut.
Of course there is no electricity (torches are provided) and running water (water is provided). But you have lovely balcony, sweet smell of the forest and villa with lovely swimming pool. You won't want to come back to civilisation. Perfect for romantic hideaway!
