19 year old girl, looking for flatmates and accommodation in barcelona for the first term to of uni

Heyyy I am a 19 year old girl from the UK, going to be attending first semester at Barcelona university, I am looking for probably an apartment or university residence near the uni, with a group of people to live with, around 4-6. I am looking for roomates who want to explore and go out. I would like to spend my time in barcelona making friends and having fun. Currently I study Spanish and Italian at Cardiff university and will be leaving barcelona in second semester to go to Italy, so only need people staying for first semester. I am sociable and always down for a night out or a cheeky adventure, I am looking for people I will continue being friends with, I like going out, concerts/festivals, trying new places, also wanting to explore other places around barcelona to travel a bit.
