If you need a short stay in the Teglholm part of Copenhagen, I can recommend Anettes flat.
It is an exciting new part of the city, a very youthful population, with a network of canals, small coffee shops and well supplied with supermarkets.
We had to spend the weekend helping our son to move, and Anette was super easy to communicate with, friendly and flexible regarding arrival and departure. Kitchen was well equipped, and the flat spotlessly clean. The bed was not king size, but my wife and I found no problem with that.
