24 year old spanish student looking for accomodation in Mannheim, or anywhere close to Quadrate.

I am a Neuroscience Master's student that come from Spain looking for a shared appartment close to Ludwigshafen - Mannheim. I am going to spend some time in Mannheim while doing my MS final project. I am keen on football, sports in general and I like to hang out with friends, meet new people from different races, nationalities.  I am looking forward to being in such a university environment so if you are interested in sharing an appartment,please contact me.  Better if you do not smoke, please... I am a bit reticent with that.
