19 year old Erasmus student, looking for an accommodation or roommate in Istanbul (Beşiktaş)

I'm looking for an apartment near Altınbaş Universitesi (Gayrettepe). I will be in Istanbul doing my Erasmus from Mid September until probably January/February. I'm a calm and tidy person, but also very sociav,e & fun to be around with and I would like to live in an apartment with fellow Erasmus Student or Turkish Students. I'm living in Berlin but as I have turkish roots I can also speak a bit turkish. Feel free to contact me, if you are also looking for a roommate at the same time period or have any accommodations or student houses that are free at that period of time :)
