Looking for a room in Köln!

My name is Szymon, I'm 23, oryginaly from Warsaw, Poland. I'm composer and guitar player. At the beginning of October I'm starting my master studies at Hochschule fur Musik und Tanz in Köln and I'm looking for a place to live. I would like to find something not very far from school (Unter Krahnenbäumen 87), I can pay around 250-500 euro, but can be also less or more. I'm travelling and working a lot so I'm not used to spend a lot of time at home. I can speak english fluently and I speak a little bit of german but I'm learning. I'm interested in all of art forms. I love biking, reading books and watching movies in my free time. I'm kind of social person and I'm very open to meet new people. I don't have any specific requirements for flatmates. I have experiences of living abroad with foreign people because before Köln I was studying in Denmark.
Another important thing: My best friend is also coming to Cologne for studying with me, so if there's a room for two or you have two free rooms in your flat it would be perfect opportunity for us!
I'm open for all propositions!
