We were lucky to be able to book the garden house on the same day that we were flying to Berlin, and didn't regret our decision. It was in perhaps 15 minutes walking distance from the airport, in a very quite neighbourhood, and we enjoyed as much of the short night (early flight the next day) as we could.
The place is decorated in a rustic fashion, with lovely old-school amenities and decorations - especially the old board and card games were super endearing to me.
Thanks for your hospitality, and all the best!
