Long term room for young female professional

I am a 23 year old on a graduate job in the City of London, therefore looking for a flat to share with ideally other young females working in office too. I am very very clean, tidy, friendly and like going to the gym, cooking, cafes, shopping and for drinks so ideally I would love flatmates who I could be friends with!!! I also would like a flat with more than 1 bathroom if there are a couple of us or more, or an en-suite and am looking for a non GF flat, with a double or single bed in a commutable area.
