Getting to the EPFL
From the Lausanne Guesthouse, the easiest way to get to the EPFL is to walk to the M2 metro across the street from the Gare. Go one stop in the direction of Croisettes to Lausanne Flon. Then transfer to the M1 towards Renens Gare, and get off at the EPFL stop.
We will be meeting in the ELA1 auditorium, which you can find on the EPFL campus map here.
