Overall, Julian’s flat is a nice, clean, and convenient place to stay in Berlin. About a 5 minute walk from the U-Bahn station and within walking distance of a tasty bakery and some other restaurants - but definitely on the quieter side outside of the busier neighborhood centers.
There’s plenty of room for guests and substantial amounts of kitchenware (and a huge kitchen). The two single beds do creak when moving quite a bit and some of the kitchenware could use a deep clean, but overall, would stay here again.
