Peter is a great guy; you feel like you are staying with a cousin. He's cheerful, smart, polylingual, and curious about the world of his guests.
His place is in a quiet neighborhood easily accessible from the airport. The room is large; the wi-fi reasonably fast; the neighborhood quiet. You can walk to the Geneva old town in about 15-20 minutes, and to the train station in about 15 minutes. There's also nearby bus stops. For those traveling by car, there's an underground car park pretty much in his back yard.
