23 years old boy, looking for an accomodation in Bremen

Hi everybody, I'm an Italian young and nice guy that has to spend 6 months in Bremen to complete my Master Thesis. I'm attending the Space Engineering course at Politecnico di Milano. I'm a quite and not noisy person, who loves sport and music. I'm also quite precise and clean because I had already experiences to stay alone away from my original home. I prefer an accomodation where I can be alone but if this is not possible and there are shared flats I hope to find roommates that are as clean as possible like me and speaking English since I'm not ready yet to substain a German conversation.
