We had wonderful days in Katjas appartment. We didn't meet in personal but the contact was very easy and uncomplicated. Katja has a really cosy appartment with an gorgeous balkony looking in a large green backyard an over the roofs of kopenhagen. Everything was clean and neat, Katja even left us fruits, juice and milk to help ourselves. The flat is in perfect walking distance to downtown and close to norrebro Station. Since we had a child with us it was even more perfect that a playground was right next to the apthouse.
In case of visiting kopenhagen again I would do the booking again at Katjas apt for certain. :)
