HOTEL is offering the ultimate getaway for weary travellers - invisible rooms.
An illusive hotel in Sweden is putting visitors in touch with nature with its one-of-a-kind tree houses.
Each room is made of aluminium and covered in mirrored glass, as well as being stuck 50ft up a tree.
Guests can only reach their rooms by a rope ladder - if they can find them.
The mirrored walls are specially designed to 'disappear' into the landscape by reflecting the woodland canopy surrounding them, as reported in the Austrian Times.
Each room at the Harads Tree Hotel contains a double bed, kitchenette, bath, living room and roof terrace.
A transparent ultraviolet colour - visible to birds - has been laminated onto the glass panes to stop birds flying into them.
Owners Britta and Kent Lindvall wanted to bring guests closer to nature and turn away from the normal concept of luxury hotels.
"It's a lovely place," said one local. "If the guests can actually find it it should be very successful."
