Spanish 21 years old girl, looking for accommodation in Athens

I'm Laura, from Murcia, Spain and am doing a three months intership with the Erasmus program. I'm a really outgoing and fun girl, love to travel and make friends, and I'm looking for rommates who are up to enjoy to the fullest their experience in Athens, nice and social. 

For the accommoddation, I'm just looking for a place near the centre of Athens, with three or four rooms so I get to have a few roomates, and a single room for myself.
