prospective student in Gottingen, looking for accomodation

A social introvert that values privacy, soltitude and quietness. I'm in Gottingen for my masters degree and been in Germany for a vacation before. My German isn't bad at all although i'm more comfortable in English. I'm neat and as a biologist, I learned to appreciate extra cleanliness. I wish I could find a private accomodation with a welcoming family or a flat mate!
