Very good practical apartment and location for a stay in Berlin. Outside the centre but very close to easy transportation and plenty of amenities nearby for a morning breakfast before heading deeper into Berlin. Apartment itself has everything you need. It’s no frills/simple, but comfortable, warm, practical, and clean.
My only real negative is that as a light sleeper in general you do get a bit of noise now and then late at night and occasionally in the morning. It’s on a side road but you can hear cars pass, people talking as they pass, and the train. Bits and pieces woke me up from time to time but it was nothing sustained. Normal or heavy sleepers should be fine and it didn’t impact my rest overly and still enjoyed my stay there and would recommend.
