Staying at a unique hotel with breathtaking views of otherworldly landscapes is many vacationers’ dream that can easily become a reality. The location and accommodations of certain lodgings may even astonish the most experienced travelers. When four boring walls, a large bed and a mini-bar fridge are acceptable but not exciting, use your imagination and book a cave. Not all underground rooms are equal. Some are luxurious, while others are very basic. In any case, they all have their own unique history and mystery.
