I had the pleasure to stay at Julien's place for one month.
Julien and his family are exceptional people, very welcoming and will make you feel at home for all your stay.
The house is huge, with large rooms, a wonderful garden and a breathtaking view on the Saleve mountain.
Moreover the location is very convenient as it is well connected with the centre, the station and the airport.
I recommend this place to everyone who wants to enjoy Geneva, both for a holiday or for a longer stay (work/study).
