Two ways to find an accomodation in Montpellier. The first way: go here, and use the search engine (on the right): try for example the "hotel" category. The EHBE conference will take place downtown, within the historical and animated centre. Thus the best choice for location is "Centre". The conference centre is close to a tramway stop (Place Albert 1er), thus any location close to this tramway line (number 1) is also convenient (a general map of the tramways is available here). The second way: to access visually the location of hotels (red dots like below), try here, use the right menu and choose "Centre historique de Montpellier" to get a map as below.
