We had a lovely stay at Margrethe's place. It is very well located, about 8 minutes walk from the Norreport metro which links directly to the airport, walking distance from central sites, but based in a quiet street. Their apartment is lovely, Margrethe and her husband work from home, so you get that old style airbnb feeling of staying with local friends. We had a lovely dinner with them one night, which made our stay special and they were helpful with tips.
