We enjoyed staying at Annas place very much. It is a super-central location in the heart of Nørrebro. Everything is very near. The flat is well equipped and neat looking. The location has a minor disadvantage, we thought; it is indeed very lively located on ground floor in a park-like courtyard making it a bit noisy and very exposed to bypassers. That was not a big problem since we did not stay inside much of the time, however I would have expected it to be even more quiet. (To be fair: we just came from the remote Faroe Islands and were being used to extreme silence. Contrast effect.)
All over I can strongly recommend a stay at Anna's place for a good urban experience of Nørrebro!
