I recommend this place to everyone who wants to spend their weekend in Geneva.
This place locates close to the historical part of the city. You can find a nice park just a few minutes from the apartment. A grocery shop is just in the same building. Also, the building is close to public transport (busses, trams, and city train stop).
Virginie is a welcoming host. She replies fast and provides you with all the necessary info.
The apartment is big, and cosy, with large windows, so it is always bright inside during the daytime. The kitchen has everything you need for a few days' stay. You can cook something if you want.
So, great place, great host.
