Looking for an ensuite to stay during weekdays

I am a palaeontologist in the British Antarctic Survey in Cambridge.

I live in Oxford and will be traveling back to Oxford during the weekends, so I am looking for a not-too-expensive place in Cambridge to spend the weekdays at. (Monday evenings to Thursday evenings - flexible).

I am sociable, have traveled and lived in a few different places in the world, am outdoorsy, love nature, and love cooking for friends. I like a mix of doing my own things, but also love getting to know new people.

Since I won't be around in the weekends, you will have your own space back in the weekends.
