We stayed a few nights at Mejse's appartement and we enjoyed it. Everything as expected, we felt "hygge". ;) Nice vibrant area, not far from Norrebro "center", we always went by bike sharing.
The only thing which was missing was enough toilet paper which Mejse forgot and wanted to provide but didn't so we needed to buy it ourself.
Another thing worth mentioning: If you like to sleep in full darkness, keep in mind that this flat has only really light curtains ;) Early summer sunrise in Copenhagen always made us wake up really early. ;)
All in all: Fully recommended.
