Student looking for flatshare in Berlin

I am a student from London, studying at Berlin Freie University for the year. Having only visited Berlin before on holiday, I am looking to find a flatshare with a vibrant, mixed group of people who have some tips and advice for the city. Any German speakers to help me brush up on my knowledge of the language would also be greatly appreciated!
I am studying literature, and this extends to an particular interest in the arts such as cinema, theatre, and music.
I am currently staying in temporary accommodation in Berlin, so it would be very easy to meet up if you are interested in finding out more about me. Let me know!
