Have you ever stayed in or lived in such a tiny home?

Norway winter , had -18c some nights , still February will get colder , lot's of snow . I live in such a tiny home yes ,.. trying to survive the cold . I keep some water in the electric cooker , so at least i can make a coffee in the morning .
When i sleep the fire dies , the cold creeps in , and everything freezes up .
