10. Sala Silver Mine: The Mine Suite – Västmanland County, Sweden
Time to go down underground, but not to the London Underground, but literally down under the ground. This hotel is built in an old silver mine in Sweden. Leave your troubles on the ground and climb down under into this amazingly preserved silver mine. Your cell phone won’t work at all, but who needs a phone when you are surrounded by glimmering silver!
This is the deepest hotel in the world and is located 155 meters under the ground in an old mine that worked for more than 500 years! When it was still a mine, it wasn’t a very pleasant place to sleep in but these days though it is very comfortable! Now you can properly enjoy the former mine without getting sick!
