New student searches a room

Hi, I am Kate from Ukraine. I am searching a warm room. I'll come to Aachen to study System Software Engineering (Master program). I have some experience sharing accommodation, I have been living in a dormitory for five years already with 4 people in a room. I am a neat and friendly person. In a free time I love to go out, go jogging or to have a chat over a cup of tea/cider bottle).
I am going to study at the RWTH, so I need a convenient way to reach it from an apartment. I have just started learning Deutch, but I really willing to advance my level.
