A new hotel has opened in the heart of Madrid proudly declaring that it's complete rubbish. More of a wooden shack than a five-star establishment, the walls of the Beach Garbage Hotel are strewn with detritus dragged up by the tide, recovered from landfills or snapped up at flea markets.

Among the wall decorations: Plastic drums, wooden frames, musical instruments, striped socks, tyres, and children's books. In the five rooms there are street lights, wobbly sideboards, and torn Persian rugs, ready to welcome the lucky winners of a Facebook competition whose prize was a free stay.
