Cozy and perfectly located flat! My wife, my daughter (1 1/2 years old) and I stayed one entire month in Loretta's flat and we loved it. It's just around the corner of a U-Bahn station that connects to almost everywhere in Berlin. The neighborhood is absolutely nice and safe with many restaurants, cafes, stores and things you would need either if you are staying a couple days or more time.
Loretta is such a nice woman and she was always pending of our needs, I'd definitely stay there again and recommend it as well.
