A visiting doctoral student at Oxford, OX1 3TA

I am a visiting doctoral student from China, currently studying in the Department of Chemistry at the University of Oxford. I am looking for accommodation within a 40-minute walking distance to OX1 3TA. As a student, my budget for rent, including all expenses, is £600 per month. I do not mind the size of the room, as long as it is affordable and close by. I do not smoke, drink alcohol, or host parties. I am easygoing and friendly.
I plan to rent from May 15th to January 15th. If there is a suitable house available, please contact me immediately. Thank you very much for your assistance.
