The apartment is a masterpiece, you can see that the hosts put a lot of soul in it, and they are very pleasant responsive people!
The hosts lived on the upper floor with their children and a dog, but we practically didn't hear them throughout our week-long stay :)
The area is very quiet and relaxed, and there's an S-Bahn Station in 7-8 minutes from which you can conveniently get to the city center.
It was nice and clean inside, and we found everything we needed to cook. The only thing is that the lighting was a bit weak & yellowish, but it's okay if you are not planning to work or study in the evenings. In general, it is more comfortable for a chill touristic stay rather than some business trip :)
