21 years old female student looking for an accommodation in Athens

I am a 21 years old student from Turkey and i will be in Greece for 2 months, between 7 June and 1 August. I came here with IAESTE program and work as an intern in AUA for 5 days of the week. I am looking for shared flat in Athens, close to central parts of city (metro stations specially). Wi-fi, fridge and washing machine should be in apartment. I prefer my flatmate(s) to be female(s). Not an obligation but seperate rooms would be better.
