Klara's apartment in Norrebro was perfect for us (3 adults) and we really felt we were staying in a home from home. The apartment was super clean, and has every amenity if you feel like cooking in as well as speedy wifi. It is a bit above ground level and has easy access to a nice leafy back courtyard if you want some outside air and space. The street and apartment block are quiet, yet within striking distance of the efficient (driver-less) Metro which gets you into the centre in around 10 minutes.
Everything was straightforward and Klara left us plenty of recommendations for eating out in the neighbourhood. Norrebro itself is a vibrant, multicultural district - apparently voted Nr 1 cool neighbourhood by Time Out recently.
I can definitely recommend Klara's and we will certainly stay at her place in Norrebro when we return to Copenhagen. So much still to explore in this easy-going city.
