I had an excellent stay at Tamara's flat in Chêne-Bourg. Although I didn't meet Tamara, communication with her was clear and efficient. Her mother lives in the house above the flat, and she was kind, helpful, and available throughout my stay. The flat was well appointed, there are supermarkets nearby, and tram and bus stops, from which you can travel into the centre of Geneva in about 20 minutes, are both a short walk away.
