Room with view: Hotel room with no walls or roof in huge demand

From quirky to downright bizarre, from ice lodges to glass walls, there are number of unsual hotels rooms that you may have heard of.

For travellers looking for adventure, flower-quilted double bed and lacquered furniture of a typical hotel room is just plain boring. So here's the latest addition to the long list of offbeat hotel rooms.

In the calm tranquility of the Swiss Alps lies the newest adventure hotel.

There are no walls, roofs, or even a bathroom but there is a butler on hand to welcome new guests and serve them.

The hotel bedroom near the Matterhorn mountain has no walls or roof and just the sky and stars above as your canopy.

The Null Stern, which in German means 'The Zero Stars,' encourages guests to sleep in an exposed bed above the Swiss town of Graubunden, enjoying panoramic alpine views while you doze off to the twinkle of the stars overhead.

Amenities are sparse with just a double bed, nightstand and lamps – and the nearest bathroom is a public toilet a 10-minute walk away.

For the cost of 250 Sfr ($254) per night, guests can be immersed in nature at 6,463 feet above sea level every night between spring and fall, but bookings can be cancelled at the last minute if the weather is bad.

As of now the room is fully booked for months.

This Alpine bedroom is the latest work by conceptual Swiss artist brothers Patrik and Frank Riklin, and is part of their 'zero star' hotel concept.

This outdoors haven is explicitly designed to soothe mind, body and spirit, and take a wholly holistic approach to wellbeing.

This sleep-under-the-stars experience is literally one-of-a-kind.
