Double En suite room wanted

Hello, I’m looking for accommodation in London for the long term. I’m getting my second bachelor's degree in law at the University in сentral London and looking for double bedroom (preferably en suite) with no more then 2 flatmates, or a studio. The room should be spacious enough for desk and office chair. I’m tidy and clean (do not leave dishes in the sink, clean my room every week). I don’t smoke, respect privacy, and won’t have any visitors. I'm very sensitive to loud sounds, so I prefer do not make noise for those who around me and expect the same from my neighbors (no loud phone conversations in common space or moving heavy stuff late night). But I'm quite sociable person and would love to have a chat and share meal with my neighbor sometimes. I would like to live no further than 40 min away by tube from Oxford Circus. My budget is 1500 pounds including bills. I'm flexible about move-in date, but no later than in September.
