We had an amazing time, I would really recommend to stay at Cecilie's place! It is a beautifully decorated loft apartment on the fifth floor (you have to be ok with stairs though!), located in a super cozy area. Compared to other Airbnb's I've stayed at, you can really feel that there is some thought to the apartment, which makes you feel welcome. It is super spacious too, great for three people (with one person on the couch). There are so many nice bars and restaurants around, located in a great part of Norrebro.
