This spacious apartment in Onex made for a very pleasant stay. It has a beatuiful view of Salève from the balcony and there are a few choices for restaurants and grocery stores nearby. If you need more options then getting to Geneva is very straight forward. Access to the tram and bus was super easy. The furnishings of the apartment are new and clean but the overall decor of the apartment is a bit sparse. This isn't true for amenities. The apartment has a well equipped kitchen and a washer and dryer which made for a convenient extended stay. Celia, the host, was very responsive and was eager to make the stay comfortable. Which it was.
It seemed like I was one of the first few guest of this particular Airbnb. Celia was very open and receptive to my feedback when I left so I'm sure that future stays will be even better than mine.
During my stay (early March 2020) there was some construction next door which started around 7 am each weekday. I was there for work and I had earplugs so it wasn't too big of a hardship. But if your a light sleeper you should try to find out if the construction is still going on before booking.
