24 year old girl, looking for accommodation/roommate in Athens

Hi, my name is Gvantsa (24 y/o) and I will be doing professional internship through AIESEC in Athens. I am looking for  possible roommate with whom I can share 2 bedroom flat or looking for someone (who lives in) and rents out a nice room in 2 bedroom apartment with necessary utiltiies. I'm looking for room preferebly in city center or very close to center with metro being nearby (preffered areas would be Exarcheia, Akadimia, Pangrati, Kato Petralona, Neos Kosmos or any other somewhat central area near to metro). I'm okay paying up to 250 euros per month for room including utility bill but price could be negotiated. 

I am very out-going and friendly person.  I like to meet new people from different cultures and learn about their experiences. I love to share about my own exchange experiences as well. I love traveling and photography. I also enjoy my quite time. I am tidy and peacful young individual.
