Antje is the most wonderful host one could ask for. She answers back to your request quickly and tries to make you feel at home.
The house is located in zehlendorf, which is one of the nicest and the safest place in Berlin. Yet it has great accessability, located just a few minutes away from the Mexikoplatz station. From the station, you can get to central Berlin directly.
If you have a car it will be ideal, but it will not be too much of a problem.
I hope I will visit this place again!
