My daughter and I loved staying at #4. The location was close to the S-Bahn, trams, and buses, and two large grocery stores. The neighborhood was residential, with families and uni students but balanced with some nice places to eat (highly recommend Pinoli!) and bars. The flat itself was very clean and modern. The high ceilings made it feel very elegant and the kitchen was well provisioned. The dining table with four chairs was awesome to have too. There was no dishwasher or laundry facilities, but we didn't mind one bit. Great communication from Volke. Overall a wonderful place to stay.
