Postdoc seeking double room in houseshare

Originally from London, I'm currently living in Switzerland but will be starting a 2 year postdoc in Cambridge in January. I am looking for a flat- or house-share in Cambridge or somewhere easily commutable.

Most days I will be working on-site, but would like to find a place that I could comfortably work from home from time to time. So ideally I would find somewhere with a decently-sized double room, a desk and decent internet. I'm open to looking for places with between 1 and 4 other house- or flat-mates.

I'm a considerate and tidy flatmate who likes their own space, but would very much like to find a place where people occasionally socialise, eat together and generally enjoy each other's company. I like cooking, watching TV, exercise, and any opportunity to escape into nature for a walk or swim.
