First and foremost, I'd like to say that Kerstin is a lovely host and I felt welcomed right away! The place is as cozy as it looks in the pictures and very clean. Guests gets to have their privacy while also being able to have a nice chat in the kitchen. The house itself is in a peaceful neighbourhood with public transport just in reach, maybe a 5 minute walk.
Of course, there are rules to follow, but I think this just helps setting healthy boundaries to create a comfortable and respectful environment for all parties involved. There is really nothing to complain about! (which is a top rating in German culture haha)
