Niels apartment is great. It is well located in Nørrebro, a cool neighborhood. Bus. 66 from the central station stops 50 from the apartment. Going the other way bus 66 takes one all the way to Nyhavn. Very convenient. We used the two bikes Niels made available and rode along the green route to Frederiksberg - very nice. Niels was a great host - he met us when we arrived and gave us lots of local info. We would definitely stay there again if we return to Copenhagen.
