People around the globe have been awestruck by the world's first 7-star hotel in Dubai. At the very opposite end of the accommodation scale, the world's first zero-star hotel housed in a former nuclear bunker in Switzerland is unlikely to invoke the same level of attraction.
Aimed at low-budget travelers, spending the night in these modest surrounds will set guests back around $9 - 13. Don't like the idea of being in a windowless underground building? No problem, allowances have been made for your discerning tastes: The operators have installed a live-cam that sends images from the outside onto a large screen inside.
On the up side, in the event that war breaks out or a natural disaster occurs, you would be safer than those who opted to stay at one of the luxury above-ground hotels.
