Looking for a room July-Sept 2017 in Bern

Hi. I am doing a final year professional doctorate and will be doing a summer semester in Switzerland. I need furnished accomodation for three months (July-Sept) to share with cool likeminded mature people. I like to be social, have a chat and a beer with flatmates, but also appreciate privacy, and I'm housetrained having lived in shared accomodation before. If you have something of this nature please get in touch .
