Danish exhange student seeks room

My name is Sofie Aspinall, I'm a danish exchange student who is looking forward to start my study at Universität Mannheim, in start February. I have lived in shared flats before (a range from 2 - 7 people), and would say that I have learned to take responsibility, and know what is the more important manners when you share a home with other people.
I'm 22 years old and study art history in Denmark, but will take my last BA semester in Mannheim studying International Cultural Studies. However, this subject area does not limit my interest, and I tend to get along with people whos interest area spreads widely and far away from my own.
I will need a room from start February to start June, a room containing the necessary furnitures is preferred, as I travel with train and is limited by that fact.
