Mr.Herbert was very kind to me because it was my first time in Berlin and I was a foreigner who didn't know the area and could barely speak English or German. The rooms are very clean and warm. The surroundings are very quiet and the location is only 3,40 minutes to the center.
As for the many house rules, nothing is too difficult as long as you stay normal. I would highly recommend this room to anyone who wants to stay in Berlin.
