20.y.o. girl looking for accommodation in Berlin

Hello, I am 20 year old girl from Bratislava, Slovakia and in two weeks I'm going on Erasmus to Berlin to study musicology and media studies at Humboldt university of Berlin. I am looking for some accomodation (from 28.september or 1.october) i don't mind if the room would be shared with someone or just for me, last week I came from India after one month, so I also really don't care what the flat will look like or something :D I just want some nice roommates, who I will feel good with. And something near my school would be great. I want to focus a little on the school but I also like parties and all
