28 year old male looking for a room in Geneva

I am italian and I am coming to Geneva for a PhD in chemistry. I am just a quiet, easygoing guy. I love jazz music and I play the trombone (but don't worry, I will not paly it at home and disturb anybody). I also like to cook. I prefer to have flatmates instead of living on my own, but I also need my space so I am looking for a single room in a shared apartment. I don't mind if my flatmates are male or female, if they smoke or have pets or whatever, as long as they are nice and respectful
