Single room in Bonn

Hi! My name is Alice. I'm a student and I will spend the next six month (from October to March) in Bonn for the erasmus. I'm really excited to meet new people and to live in a foreign city! I'm a very friendly person, so I have no problems living with other people. I'm looking for a single room from the 1st October (maybe even earlier, I'll be in Bonn in the end of September) to the 31th of March already furnished, possibly in a district near the university or that I can reach by bike (I won't have a car, so I'm not looking for a parking spot). I only know italian and english: I would like to learn German but for now I ask you to please reply in english. Thank you and hopefully see you soon!
