student apartments in Spain

I lived in Granada from Sep of 2002-June of 2003, and studied at the CLM. I'm returning to Granada for a semester to take a class, and I need to find an apartment. Anyone know of a website listing only the student apartments? I'll probably end up staying with friends in Granada while I look, but I'd still like to find one before I go! My Spanish friends are looking... but you know how that goes. Muchisimas gracias por ayudarme!
