Nice appartment in a very central location. Even if Cophenagen is small, being at Jonas's place allows to go everywhere by foot (public transport are very expensive!!).
We did not have a chance to meet Jonas and had the place to ourselves. Yet he was very helpful by mail before we arrived.
The flat is nice, big and clear but not perfectly clean even if it was not dirty at all. The building is quiet.
I would recommend anyone to go to Jonas's flat and to Copenhage.
