I, my 16 month old son and my husband stayed at Martin's house for 2 nights.
It was very good location.
We passed very easily to the center of berlin by car.
Our entry and exit were both very easy. There are markets within walking distance if needed.
In terms of communication, Martin was very successful. The equipment of the house was also very good. Everything necessary is available at home. We did not have any problems with heating. Since there is a fireplace in the house, we had the opportunity to use it even if it was cold, but we did not need it.
in short, a great place to stay, thank you Martin.
