Looking for a room in a shared flat or a single room apartment

Hi, I'm Gaetano Bonetti and I am currently studying informatical engineering at the university of Palermo, Sicily, Italy. I am going to be an erasmus student in Karlsruhe for the winter semester (six months), from the first of september to the first of march. I'm looking for a furnished room in a shared flat or a single room apartment. Talking about the shared flat, I would prefer if the flat is not too crowded, like with maximum five people. I am obviously going to help with the cleaning and the housework of the shared rooms. I am going to study in the applied sciences faculty, so a position in between of the faculty and the center of the city would be perfect, but if the place has good tram/bus connection I will take it also in consideration. My budget is maximum 400 euro per month, possibly bills included. Please don't hesisitate to contact me at any time.
