21 year old looking for roommate (and apartment) for 5 months

My name is Petros (Petrouil Rabinowitz), I am from Greece and I will be doing my erasmus studies in Barcelona from February to June at least. I am an easy going person, I don't  complain easily. I am looking for roommates, easy to live with, not having a problem with guests, as long as they stay in my room. I haven't found an accomodation yet, I have to stay near S1 stations (i.e. La Gracia, Plaza de Catalunya, eixample) because I will study in Terassa. Feel free to contact me.
