24 year old girl, looking for accommodation in Geneva centre ville

I am looking for a room in a shared apartment, I am 24 years old female, I will be coming to Geneva for a physics research position. I am really social and easygoing, enjoy meeting new people from different places, but I also respect privacy and the need for alone time :) I like to do sports in my free time and hang out with friends. My budget is around 1500 CHF (but willing to go a little over if I really like the place) the room is preferably in the center (the Cornavin area is ideal). I speak English, French, Arabic, and Danish so hopefully, communication is not a problem!
