Room Wanted / Buddy-Up In Cambridge :)

I am looking for a nice room in a flat or house in Cambridge, ideally in or close to CB3. I am a young professional, working in the environmental sector, and I am looking for quiet, considerate flatmates (not overly quiet...but I do like my sleep!), ideally other young professionals or postgraduate students. I am past the partying years and prefer relaxed evenings, so it is very important I find people who are similar in that sense. I am very tidy, but I don't mind if my flatmates are a bit more chaotic than me. I love watching movies, cooking and being outdoors. I come from an international background, so it'd be great to live with other international people, but it's not at all indispensable. Apart from that I am a very open, social and happy person, so I hope to find nice people to live with!
