Looking for a flat in London

I am a 32 year old liberal gay man and working professional looking to rent a room preferably with an en-suite in or near East London/Stratford. I am a civil servant and am clean, tidy, respectful and easygoing, and am looking for like minded people and preferably other gay men. I am interested in reading, walking, nature, exercise, cooking and eating out, and the occasional night out, but am generally a quiet person. I am allergic to cats/smoke.
