Karen's apartment is really nice, a top floor apartment from which you can see the sky of Copenhagen. Very quiet (you will not hear any traffic), both the apartment and the room are super comfortable, very cosy and perfectly clean. The apartment is less than a five minutes walk from the bus stations (5A to the central station and the airport and 350S and 33 to the city centre in only 15 minutes) and a 15 minutes walk to Copenhagen two metro lines (you'll be in the city centre in a couple of minutes!). There is a big supermarket next to the house and many restaurants and cafes in the bus station street. Thus, I highly recommend Karen's house not only because of its position and the apartment itself, but also because Karen is a very kind and attentive host, ready to talk with you and to give you your privacy. She also allowed me to stay longer than the check out time and she gift me some danish chocolate candies for my return journey: she was so nice! I would definitely recommend Karen's place!
For the future Italian guests: Karen has a moka pot and her coffee is the best!
