I have been in the apartment during spring 2014, and everything was really good.
The apartment was clean, and very, very well equiped. The kitchen has many stuffs to cook, and the kitchen appliances, (Fridge, washing machine, etc.) are new.
The living room has a big sofa and all the rooms has a lot of sunlight, which is always important in Copenhague.

Regarding the location, the flat is a very good option if you want to stay in Norrebro, very close to the Metro station and bus stops.

Marfa answered to my questions in the same day, helping me with any small problem that I had. She is a good host, so I strongly recomend her!
