September rental wanted for Canadian professional

Hello all, I'm a Canadian-Egyptian lawyer currently visiting London to see friends and family and am looking for a furnished double room anywhere in or near central London (flexible on location) *for September 6-30*. I'd like to view the property and meet my prospective landlord/sharers first, and am available anytime for viewings. Ideally there would be a garden or balcony where I can smoke, and no pets. Women roommates preferred. I'm tidy and quiet. Budget flexible.
