Searching for flat share near city center

I am an American master's student studying Middle Eastern politics at Tuebingen. I am looking for a flatshare somewhere close to the city center and with friendly, social people.

I am a sociable introvert, in that I like to keep to myself and my space at times and at others cooking and sharing meals with people, having a drink, going for a walk, etc. I'm a big language nerd and speak Arabic mostly fluently, and have dabbled in Spanish and French (and now hopefully some German!). I like to cook most of my meals, keep a clean space, and am generally quiet.

I moved to Germany with my cat, Boondock, who does not have claws and is suuuuper cuddly.
