Professional looking for room to rent

I work in the film industry and I'm looking to move into London. I studied English literature at university (undergrad and postgrad) and then went to the National Film and Television School. I enjoy socialising, going out (I like electronic music), and going to gigs, but I'm equally comfortable in my own company. Whenever possible I try to find some time to play tennis and I never miss a Chelsea game. I'm very clean and tidy and like to live with people that are the same. The only regular guest I would expect to visit is my long-term girlfriend (7 years), who works as a dentist.
