24 year old student looking for a room in Barcelona

I'm a 24 years old student looking for a room in Barcelona. I will be studying in Zona Universitària so I am mostly interested in living anywhere that is less than 45 minutes away from it.  

I am an easygoing person and respect other people's privacy, I clean after myself and tend to be well organised.  I like to travel, explore new places and meet new people. During the time that I am at home, I am usually a quiet person and considering I will be studying and doing a thesis most likely I will be working most of the time so I don't think I will disturb you. Still, I'm always up for grabbing a beer, socializing and in general chilling out :) 

I am looking for a room with a desk, some exterior light would be appreciated and for a maximum price of 450€ with all bills included. Please contact me if you are interested.

Thanks
