Professional femal, 22, looking for a room.

I am looking for a double or single room in good condition. I do not spend a lot of times at home during weekdays as I work in central London and attend the gym after hours. I'm also not a party animal, although I do like to go out with friends from time to time. Not big on house parties. I am pretty easy to live with, neat and chatty, so I'd love to share a flat with someone who's similar.
