I loved staying at Sarah's place. It's incredibly charming, with a lot of creative and thoughtful touches. (As someone who was staying there for a little over a week and likes to cook, I really appreciated the cooking utensils, pots, and pans.) It's also clean. Sarah was very welcoming and responded very quickly to my messages. The best part of my stay though was the location--I loved being near the Sonnenallee. The apartment was also a 5-10 minute walk to the nearest U-bahn station; I was able to walk to the S-bahn in about 15. All in all, I would absolutely recommend Sarah's place to someone who wants to experience Berlin in general and Neukölln in particular!
