I had stayed at Mr. Karaman for 41 days, and that was a very pleasant experience. For convenience, there is a bus stop within 4 min walk. And you can take bus K and transfer with tram 14 to the center of Geneva . It will take about half an hour. And You can buy some food at the center.
Besides, Mr. Karaman is very kind and helpful. He will definitly make you feel like home. And you have to make the room clean.
All in all, the host and the room are perfect. I highly recommond to everyone.
