24 year old guy, student of architecture, looking for accomodation in barcelona

I am enrolled into Institute for advanced architecture of catalonia. I am from chennai, India. I am looking for a room along with my friend who is going to study the same course. We are okay with sharing or even a bed for 1 person is enough. We are also ok with getting different rooms at different localities.I want a nice room with good toilet facilities and I am ok with sharing. I am a very silent and respectful person. I dont drink alchohol or smoke. I get along well with people and is always interested in travelling and sight seeing
