Me and my boyfriend stayed at Claire's apartment early January. It is perfectly situated in Nørrebro in close proximity to really nice streets with cosy cafe's, eateries and non-mainstream shopping possibilities. "Inner Copenhagen" is easily accessible by bus, which departs very frequently (although it only takes about 15-20 minutes to walk the same distance).
The apartment is even prettier than in the photos, and everything is very clean. Be aware though, the apartment is on the top floor and carrying heavy luggage will be quite a workout (as there is no elevator in the building). We didn't have the opportunity to use the balcony so much because of the cold weather, but we imagine it would be really nice in the summer.
Claire as a host was very friendly and quick to reply when we needed anything. She was helpful and recommended various cafe's and eateries.
We will definitely book again next time!
