We stayed for a month in February and we had a wonderful time. The apartment was cozy, warm and well-equipped. Highlights: good quality linen, comfortable bed, good shower pressure, large bath, well-equipped kitchen (dishwasher, oven, lots of good quality pots, pans, utensils, whistle kettle, baking dish, tea towels etc), great drip coffee machine, efficient clothes washing machine, underfloor heating, quiet neighbours. We also liked having a separate toilet. We didn't like the Austrian-style large pillows but that's a personal preference. The wifi was just ok. Overall, the apartment has been very well furnished/decorated, everything was in excellent condition and immaculately clean. We even had little chocolates on our pillows! Klaus was friendly and helpful. The surrounding area, whilst not the most pretty, was convenient with supermarkets, fast food, chain stores and the subway all within easy walking distance. Make sure you try "Ferhat Doner" and visit the Military History Museum.
