The Airbnb is in a good distance to both the central station and the north station, only 15-20 minutes by foot. The Apartment is designed well and has a comfortable bed.
All in all we were satisfied with the Apartment. With one exception being a mouse that made noise both nights since it was crawling through the ceiling.
Another suggestion maybe: we would have loved to have a kettle just to make some tea/ instant coffe in the morning.
And just a notice for people having difficulties with walking: the stairs are very narrow and steep
