I can absolutely recommend Minelas place for a stay in Copenhagen. On the short walk from the metro station to the apartment, you walk past a bakery - everything there looks fantastic and tastes even better (try the kanel stang if you are into cinnamon). So that was a fantastic start. Some parts of the city are definitely within walking distance, more comfortable to get to by bike though. I got lucky, the bike shop downstairs lent me two bikes at a great rate.
Overall, a very convenient to stay there, three supermarkets next door and Minelas tips for a restaurant/pub street in Norrebro was also great. Her apartment is very neat and cozy, my girlfriend and I would come back there without thinking twice.
