I've been hosted by Line for around 6 weeks. She was an excellent Host, she gave me all the necessary informations to reach the place and once there she carefully explained me everything about the flat. Additionally, during my stay she was from time to time checking if everything was ok.
Regarding the flat I've been very pleased with it, it is a really nice place, very quiet and with all what you need to enjoy your time in Copenhagen. If you have any particular issue with walking or doing steps you might want to be aware that there is no elevator and the flat is at the top floor, but otherwise it's just some good exercise. I would definitely recommend it.
