20 year old girl looking for a place in Barcelona with other students

Hello!

My names is Elisa! I am mexican (with spanish nationality), 20 years old. I am studying Literature in Universidad of Barcelona (plaza universidad). I am responsable and organized, I like american football, (soccer not so much but kind of), yoga, watch movies, go out, meet new peole, read books, listen to music (jazz preferably), go to museums, cooking, baking and photography. I don't smoke, but I don't mind smokers. About pets, I love dogs, (cats as well but sadly I am allergic). Currently I don't have a job but I am looking for one. I am not an Erasmus Student, I plan to do my whole course of 4 years here in Barcelona. 

I am looking (mainly) for an apartment next to plaza universidad (to be near my school), not a MUST, but definitely a plus. I like sunny spaces, but above all, clean spaces with just the necessary stuff, I really dislike hoarders. 

I am looking for young roommates (18-28), students or professionals both are okay to me. It would be fun to live with international people, to see their way of doing things. I don't have a specific preference (both are fine).
