40 Unique Hotels That Actually Exist Around the World (Some Are in the U.S.)

The Sala Silvermine gives you the feeling of what it must be like to live underground. Here, you can sleep 500 feet below the ground in an underground suite. This may be the quietest hotel you’ve ever been to, with no sounds of traffic, cars, barking dogs, children, etc. You just may get the most restful sleep you have ever had (provided you’re not claustrophobic).

This is another hotel that may not be best for those with claustrophobia, as it is an enclosed space underground with no windows. But fear not! You will not actually run out of oxygen, despite your biggest concerns. This may just be the romantic getaway that you were looking for if you’re in desperate need of some peace and quiet.
