I contacted Nanna on behalf of some friends for staying in the apartment for a couple of nights. She was very helpful and quick in the response, she even manage to find a way for my friends to get in the apartment even though she was out of town the arrival day.
Comments from my friends on the apartment were good overall, they were very happy with the location and information on how to park the car in a no paying area very close to the apartment. Also, very happy with the bikes and the breakfast/drinks that Nanna provided for them. Despite, not having being myself ín the apartment, I think I can totally recommend to contact Nanna for a good experience visiting Copenhagen
