This mini-workshop will take place in the campus of the University of Montpellier II, in building 11 (entrance in front of building 22), room "Andromède", 4th floor (on the rhs at the end of the corridor). A pdf map of the campus is available at this link.
The University of Montpellier II is located Place Eugène Bataillon, along the tram line n°1 (the blue one) -- the square is easily found thanks to the giant "red donut" lying in middle of the roundabout. From downtown (where the railway station, or Place de la Comédie, are located), take this line toward "Mosson", then get off at stop "Universités des Sciences et des Lettres". To go back downtown, take the same line toward "Odysseum".
NB: you will have to purchase your tickets before taking the tram (ticket machines at each stop).
From the airport, take a shuttle to "Place de l'Europe", then tram line 1 (see above).
Hôtel du Parc, hôtel du Palais: stop "Place Albert 1er".
Hôtel Mistral: stop "Gare Saint Roch" or "Comédie".
Hôtel Lapeyronie: stop "Hôpital Lapeyronie".
