One room seeking for a PhD male Vietnamese student

I am a PhD male student from Vietnam. I am looking for one room since October 2014.

The room can be in the Student Camp/domitory or WohnGemeinschaft. Renting cost (with heating, internet and utility) is less than Euro 350 per month.
It should have a kitchen, may be shared to others so I can cook
The room locates in Bonn/ Cologne or nearby, convenient to public transport.
The ideal location is surround Bonn University or subburb (Koeln Sued,Bonn Sued, Poppel, etc..).

I can speak English, German. I am more than 30 years old, friendly, ruhig and humorious. It is nice to live in intercultural environment so we can learn from each other.

Please contact me if you have one room or any information that can be suitable for me.

We can discuss and/or negotiate more about the room, conditions, and any other things later

Thank you so much for your information
