Looking for a room for long term near Haggerston

I'm looking for a room for rent, not too far from Haggerston station in London. I've just been offered a job in this area as a senior engineer for a musical instrument design company. I'll start on the 1st of September so I'd like to have moved in by then. I'm also a musician but I do all the music stuff with electronic instruments wearing my headphones so it won't bother anybody. The room should be of reasonable size preferably with a desk. I'm 30 and would prefer living with people of about my age but I'm sure I'll get along with anyone. I have a car so I'd prefer some place to park nearby.
