While other hotels are concerned with building great walls with really nice interior designs, Null Stern, a hotel Switzerland is doing otherwise.

The hotel which is about 6,463 feet above sea level in the middle of the Swiss Alps has no walls nor roof. It's an open air hotel with a bed nestled into a crevice on a Swiss mountain, bedside tables and lamps to light up your night and the bathroom is about 10 minutes walk away from the restaurant.

While other luxury hotels strive for a five-star hotel, in Null Stern, meaning 'no stars', the 'only star is you'.

Frank and Patrik Riklin, the brains behind this unusual hotel are known to be conceptual artists that use hotels as their means of expression.

Head of hospitality Daniel Charbonnier explains that their goal is: ‘To put the guest at the centre of the experience and to focus on the intangible by reducing everything else to the minimum.’

Well, I guess they did achieve that in this hotel.
