Kakslauttanen, Finland. 
It’s my dream to see the Northern Lights and I think I’ve found the perfect location to see them… Here’s some more information for anyone else who shares my dream:
The Glasiglus have a dome made of special thermal glass, making for a normal room temperature and whilst the air outside sits at temperatures below -30°C. Thus, you always have a great view of the sky, to observe the many stars or northern lights. Each of these igloos is equipped with a bathroom and a luxurious bed.
There’s also an Ice Gallery, where various snow and ice sculptures are exhibited by international artists!
You can stay anytime from December to April.
