23 year old girl looking for accomodation in Durham

Hi, I'm  a postgraduate erasmus student at the last year of Msc in Finance. I'm 23 years old and i'll stay Durham from january to june. I'm searchinh for a double room in a home shared with other postgraduates student (indifferent age and gender). My course at University of Siena is fully in english so i'm practice with the language but I want to improve myself and I prefer stay in a house with people of different nationality. I woul find a house not too far from the University Business School. I hope to find as soon as possible an accomodation. Thank you in advance.
