Philippe's flat is large and quite comfortable with all the amenities you might need. The pullout bed is particularly handy. It is also well connected and very near a number of busses - even one that goes straight to the airport. There are also many shops and a gym nearby.
I stayed at Philippe's place in the summer and it was very hot in the city. The flat is next to a construction site and on very busy street, so whenever I opened the window there was a lot of noise and sometimes even the smell of gasoline. Also in the bedroom, the only way to get ventilation is from the door to the terrace, which it would be unsafe to keep open all night, so I rarely got a good night's sleep, unfortunately. This could be resolved with some fans, perhaps.
After a very busy couple weeks working and travelling, I got confused and although I told Philippe that I would leave at 9am, I remembered is as 10am, so left about 45 minutes late. This cause a problem for Philippe, as he had a cleaner ready to come is exactly at 9am to get the place ready for the next guest at 12pm. He made it clear to me in phone calls and texts that this was a major problem for him and I apologized. It was really not my intention to cause such a problem for the host.
I recommend Philippe's flat if you are in Geneva in the winter time, and perhaps for holiday and not for business.
