How to get here
From the main station Genève-Cornavin take Tram # 18 towards Carouge.
Get off at the stop (Carouge) Then take bus # 41 towards Petit Veyrier (on the other side of the crossings).
Get off after one station (Fillion) Instead of bus # 41 you can walk on Route de Drize (on left side) for about 300 meters and keep left on Chemin de Pinchat (about 7 minutes).
The GAP building is on the right side just after a TPG bus # 41 stop called Fillion.
Note that some GPS devices tend to mix up our building with the neighbor. Be sure to check that you are at number 22 in Chemin de Pinchat
