The Balea Lac Hotel of Ice is located in the Fagaras mountains in Romania. Entirely made of ice, the hotel offers accommodation where the temperature is between -2º and +2º C (approximately 28º and 35º F). Ten double rooms with king size beds book for £35 ($45.73) per person.
The hotel offers amenities like most other hotels such as a restaurant and bar. My only question is who would pay to eat, drink, and sleep in the cold?
