I had an awesome experience staying at Oscar's. He is always an interesting and nice person to talk, and above all very considerate - he is willing to go beyond the nominal duties of a host to help you out. The apartment - especially the bedroom and the kitchen - is small but very thoughtfully laid out (I'm impressed, for example, by the ample well-placed light sources in the bedroom), and the multiple balconies are a huge plus. The neighborhood (Carouge) is arguably one of the nicer neighborhoods in Geneva, and the apartment is well-served by public transportation: stop for tram 12 and 18 is merely 2 minutes away; stop for tram 15 and buses are also not very far. I would love to stay at the apartment again whenever I come back to Geneva!
