30 year old female professional needs new home

I am looking for a double room in a flat or house shared with one, two or more people, the most important is that we really get on.
A little bit more about me: I am a 30 year old professional - a founding partner of a communications agency based in London, that means I work quite hard but also need a nice and friendly environment to balance this when I come home in the evening. My weekends are spent seeing friends, running, cycling or chilling at home.
I used to live with my brother but he is now getting married and therefore we both decided to leave our current flat (which will also help me shorten my commute as we currently live in Kent).
I would love to hear from you if you have a nice cosy room for me, and if you are fun, friendly and respectful people!
