Absolutely wonderful location right in the heart of old town. It was very easy to get around with train/bus stops just down the road + on foot. We were also relatively comfortable, even in this heat! Having the fan and blinds pulled during the day helped a lot.
We had trouble getting in at first. The bottom (main) door is unlocked but the handle doesn’t turn, you just push it open. We also had an issue unlocking the apt door, you have to twist the marked key two full turns in the lock just below the door handle before opening.
Wifi was fast and reliable, it even worked from the little Italian restaurant across the alley (which we highly recommend, regardless!). Philippe also provided a plug adapter which came in handy because we brought the incorrect one.
The other reviews mentioning the noise are not exaggerating. There is a club just across the alley that is open 7 days a week until 5:30 AM. While the club itself can’t be heard, the club goers waiting outside of it sound like they’re right outside of your window. We were in no rush during our time in Geneva, so sleeping in after a poor night sleep wasn’t a problem for us, but if you have strict plans, etc. during your time here you might want to bring some ear plugs!
