We absolutely loved staying at Julia's apartment! We chose it mainly because of the location, which is fantastic - very convenient to the train, and on one of the prettiest blocks we encountered in all of Berlin. There are tons of great cafes, shops, and restaurants nearby, and the area has a fun, relaxed vibe. On top of all of that, the apartment itself is gorgeous and so comfortable - nice bathroom, comfy bed, and a huge kitchen and living room area. It is a walkup, but we didn't mind the stairs. We'll definitely stay again!
