File this under wildly wacky hotel experiences. Design Taxi has uncovered “the world's deepest hotel room” at the Sala Silvermine in Sweden. Located 500 feet underground, the so-called “Mine Suite” is “surrounded by winding galleries and thrilling cavities”-- to quote the official website.
When you arrive, you get a guided tour and then a basket brimming with goodies like cheese, crackers, fruit, Champagne and chocolate. The following day, breakfast is served by one of the mine's guides, then you'll be led to ground level again.
Note: A stay in the Mine Suite is not for the faint of heart (or easily chilled). The toilet is located 160 feet away, and it's quite cold in the mine itself, so warm clothes are advised. Though the Mine Suite is heated to 65 degrees.
