85 euro for a single room and
98 euro for a double room,
breakfast included. In order to benefit from this special offer you can either book your room yourself by sending a completed Fiche de Réservation to the address H2200-SB1@accor.com, or you can contact the organisers, in which case we shall be happy to book the room for you.

Venue

The conference will take place in Hotel Mercure, Boulevard de Lauzelle 61, Louvain-la-Neuve.
