I had a great stay in Gultekin's apartment, which was spacious, clean and comfortable, with a very well-stocked kitchen. You are near to some nice parks in Geneva while also being conveniently close to the city centre/train station and two very big supermarkets.
If you are planning to work, you should be aware that there is no wi-fi (as is stated in the listing), but I think this made my stay even more peaceful :)
Thanks again!
