You may have a hard time but I think you can find something. It may not be very close to school but try. The neighborhoods in the Segundamano to look for are (starting with the closest to the complu) Moncloa, Metropolitano, ArgÜelles, Cuatro Caminos...then futher up from Cuatro Caminos you should try Tetuan. The rent prices will be cheaper there and it's not too far from school. Also, consider living on the grey metro line (#6), it's a stright shot to school and you have more choice as to where you can live.
