This is a great place where you can't go wrong.
Norbert is a lovely gentleman who respects your privacy.
The location is good in that you have access to U-Bahn Johannisthaler Chaussee Station, which means you will get easily in and out of town.
You can tell the care Norbert is taking with his guests. The place was clean, the linen fresh, everything was tidy and in working condition. Not only do you have access to Netflix, Amazon, internet radio, etc. but he made sure that you are safe too. You will find smoke alarms, a fire extinguisher and a fire safety blanket among other things, all within your room. As far as I can tell, he adheres to all fire codes and other regulations. In all my years using AirBNB, this is the first time I have seen someone who took this topic seriously. Thumbs up!
The room is private and cosy. Nobody disturbs you from the outside and you have many options to heat or cool the room, depending on whether you find yourself staying with Norbert in summer or winter.
Personally, I have to say that Norbert is a lovely person. He is always available when you need him and stays out of your way when you need some time for yourself.
He and his place exude a charm that is very specific to Berlin.
You will not regret staying with Norbert. Great guy, great place! Full ratings across the board!
