The private igloos at Hotel Kakslauttanen are made with a special thermal glass, which keeps out the frigid cold and lets you view the spectacular Aurora Borealis from the comfort of your bed.  If you are not bothered by the cold, you can spend the night in a snow igloo where the temperature stays between -3°C (about 27°F) and -6°C (21°F).
