23 year old student (female), looking for accommodation in Athens

I am a 23-year-old student from Norway looking for accommodation in Athens, Greece. Going to stay in Athens from late December until early June 2017. Looking for an apartment near the center. I am the social kind. I am easy to get to know, and not afraid to get to know other people. I am an outgoing person who loves to experience new things and new people. That is one of the reasons I am choosing to go to Athens.

I am looking for a secure place, not too small. Would love to have a balcony!

I prefer that my roommate is the same gender as I am; female. Would have been nice to share an apartment with another student. Does not matter where she is from, it is always good to get to know people from other cultures! If she has a pet or not does not matter either, I like pets.
