I had a pleasant stay at Loretta's place on Nollendorfstraße. The apartment is comfortable, bright and situated on a quiet side street, whilst being so close to the heart of Schöneberg. Furthmore, Lorettta was a great hostess. My luggage was lost en route to Berlin and so she let me check in early - giving me advice on where to buy essentials such as toiletries and an iPhone charger. The apartment is on the fifth floor of the building - no elevator - so be prepared for a workout. Personally, I would highly recommend this apartment.
