Accommodation is not arranged by the conference organizers. Each participant is invited to do their booking individually at one of the many downtown hotels of Rennes. For your accommodation, you may book a hotel in the southern or northern city center, as you will never be far from a metro stop or a bus stop.
The city of Rennes is well served by public transport with its 2 metros and numerous bus lines making Beaulieu campus accessible in 10 minutes with the new metro line (B) and up to 20-25 minutes by bus. Suggested itineraries to reach Beaulieu campus from the city center are detailed on the Venue page. A list of accommodation options is available at the Tourist Office Site of Rennes.
