Cheap digs … the Null stern Hotel in the small town of Sevelen, Switzerland, will become the world’s first ‘zero star hotel’ when it opens in 2009.

Going underground … the hotel has been developed inside a former nuclear bunker.

Close shave … guests can swap expensive luxury hotel add-ons for prison-style essentials for just $14 a night.

Sleep company … visitors are treated to dorm-style accommodation with Swiss army-standard beds.

Safe haven … hotel guests will be safe from terrorist attacks in the cosy Cold War bunker.

Up-grade … visitors can upgrade from dorm-style accommodation to their own room, complete with unpainted concrete walls, for $39.

Family affair … guests will receive a complimentary pair of slippers to venture across the cold concrete floors and mingle with fellow inmates.

Also on offer is a set of earplugs to drown out the noisy ventilation system.

Bottle it up … the converted nuclear bunker is too expensive to heat, so guests are treated to free hot water bottles to keep them cosy.

Wheel of unfortunate … like the rest of the hotel, the interior artwork is a lot to be desired.

Face value … and the exterior isn’t exactly inviting, either.

We’re open … at least they went all out on advertising the hotel.
