Norbert is a good host but few points one must consider prior to accepting his place ( we knew them). Connectivity to hbf is a big problem and that too with city center. No direct S or U lines. Very far from city center and so huge problem if you are leaving early morning. There is a cat at the property but you have to keep your room closed all the time otherwise it may enter your room and cause problems. There is only one window which opens in a small balcony shared by host so a couple will not like to keep it open and then room will be stuffed.
Good points
Internet radio is a big plus point. I could listen to My favourite singer Mohd Rafi radio all the time. TV is there and so is washing machine.
Neat and clean
Close to U bahn station 400 meters but only U 7 line
Nicely maintained kitchen.
Room description exactly as shown in photos.
Nice garden outside. Eatables easily available near by. Wifi fine. 6 steps in stairs . Hot water available in bathroom all the time. Would recommend to single guest and that too with readiness to stay away from city center..Very much away.
