We went to Copenhaguen three friends just for a few days and had a great time, Maria's house is really warm and confortable. And she was very nice to us, when we arrived she had made a list of good places to go aorund the neighborhood, and even had localized them in the map. The flat is very central, just a 15 minutes walk from the city centre.
I totally recomend this place to stay, and Maria was a great hoster.
