20 year old student looking for accommodation in Barcelona city

Hello! I am a student studying Spanish and TESOL and Nottingham Trent University in the UK and I am an erasmus student doing my third year in Barcelona teaching English to children. I'm originaly from Newcastle in England. In my spare time I like to socialize, go to raves, listen to music and go to the gym. I also like chilling with friends and going our for meals. I'm a keen learner of Spanish and want to practice it a lot more when I come to Barcelona! I am looking for a double room specifically in Eixample, Les Corts, Sants or an area near!
