Professional Female seeks a double room

I am a professional female aged 24 looking for a double room in a good location close to my work. I am available to move July and have a rough budget of ?550pcm. I would Ideally like to share with 2 people instead of a big number of people, however I am flexible and easy to live with so more people wouldn't be a deal breaker! I would like to live with respectful like minded people who are not too noisy in the early hours!
