There are a lot of amazing hotel experiences out there, but none are quite as unique as the Sala Silver Mine in Sweden.

And if you choose to stay in the suite, you better not be claustrophobic.

For $660, you'll be lowered into an old silver mine where you'll be led to a cave-like hotel suite 500 feet below the ground.

It's in the deep cave where you'll experience total solitude until the next morning, when you'll be given breakfast and then guided back into the sunlight.
