23 year old girl, looking for accommodation in Barcelona

Hi! I am a 23 year old girl from the United States and I will be moving to Barcelona near the end of March for work. I will be working on a project with a local company for about 6 months (maybe a month or so longer) and need some accommodation. I travel around a lot and always love meeting new people! I will live with male or female roommates, I'm not picky! I'm pretty laid back and enjoy hanging with friends, going adventuring, going out, and I'm especially looking forward to being close to the beach in Barcelona! (I am a huge fan of beach volleyball and I'm always down go play). I'm very sociable and easy to get along with. In the past I've become good friends with whoever I'm living with, it's always more fun that way, don't you think?
