The house has a very transport connection. The metro from the airport goes directly tho "Amager Strand" from where you walk just 2 minutes to their house.
They described the way very well, so we had no problems to find it.
The hosts were in holidays, so we couldn't meet them, but another woman gave us the key.
The room is small but the bed is comfortable. Unfortunately we were not happy with the cleanness in the house. It smells of cigarette smoke and the floor (in our room, the bathroom, the corridor and the kitchen) was dirty. Especially the toilet and the shower did not look very cleaned. In addition to that, our bedclothes were stained and not clean, just as parts of the kitchen (cupboards).
So I can recommend the room because of the location and it's an acceptable option for a short stay, but if you attach important to perfect cleanness it won't be the best choice.
