Sala Silvermine is known as the deepest hotel room in the world at 500 feet underground. It can only be accessed through a mine lift shaft. As you can imagine, there is no room service or anything you’d expect in a luxurious hotel, except a comfortable double bed, silver furnishings and champagne platter. It’s cold and damp, but absolutely gorgeous. One night in the bizarre suite will cost about $500. Sala Silvermine, as the name suggests, was a mine, which produced about 3 tons of silver a year used mostly for coins.
