We had wonderful days in Simons appartement. Simon was very helpful during our stay. The appartement has a great location, very close to U-bahn. We placed our car in a free parking lot outside the town and bought city-pass to go by train, U-bahn and busses. And then we rented bikes. That was a wonderful and easy way to enjoy Berlin. We also went to the Olympic Stadium for swimming. The appartement was cosy, huge and had all we needed for at great stay. Berlin, we come back.
