Room for January-February (or longer)

Hi there - I'm a 28 year old Australian (with a UK passport) living in the Brighton, UK at the moment. I work freelance as a videographer filming and editing promos for corporate companies, fashion/music videos and fictional short films. I'm looking for a bright, sunny room with a double bed and a friendly atmosphere :) I am careful to keep shared areas clean and tidy and like cooking dinner and having a chat or a pint with my flatmates. I came to Berlin for the first time a few weeks ago and loved it - after living all around the UK for 7 years I am looking for a new place to explore as I love to travel! - I am looking for a room for at least two months while I go to job interviews and continue German lessons. When I'm freelancing I am usually at the local cafe editing with a coffee :)
Danke!
