Master Student is looking for accommodation in Frankfurt or Rüsselsheim

Hello everyone!! I'm from Ankara, Turkey, 27 years old.  I'm looking for a room to rent in a shared apartment. I will study from September 2015 to March 2016 at Hochschule RheinMain University of Applied Sciences in Engineering Faculty (Environmental Engineering Master Degree) in Rüsselsheim and I will need an accommodation Rüsselsheim or Frankfurt. If flat is close to the university would be ideal. I am a very social girl and with no problems of adaptation. I am bass guitarist and i have music band in Turkey i would like to play there too. So if musician people contact me it would be great.  I am also not so rich so I'm looking for a rent that does not exceed the 300 euro. Thanks in advance !!! I dont mind if my flatmates are girl or boy. I have lived with boys for years here :)
