As Sunniva & Sebastian had experience hosting people with couchsurfing they were very open-minded and helpful in any way possible. They're really flexible in terms of arrival/departure and the flat is very close to the airport, which was exactly what we needed. They are very kind and interesting people, we had great conversations not just about what to visit but about the local and more social part of living in Denmark as well. I highly recommend staying at their place :)
