I am looking for comfortable room in a nice residential area

I want to find comfortable room with a nice and quiet atmosphere. Can be far from the center of Munich (50-150 km) Small village the same suit. The main thing that was comfortable and reasonable price and must be a high-speed internet.
I plan to stay in Munich for a long time and teach the German language. At the moment I live in Strasbourg.
A little bit about myself: I was born in Ukraine and lived a long time in Kiev. Due to work, I need to live in Germany and I am very happy. I have German ties. And I like the German lifestyle. I lead a healthy lifestyle and like a lot of work. My parents live in the United States and are citizens. I work in the American shipping company.
If you want, I can provide guarantee of decency and recommendations. I am very neat and decent, pleasant in dialogue, good manners.
