The metro stop is Madou. When you exit the metro if you stand at the top of Chaussée de Louvain, walk down the hill and when get to the bottom, across the street on your left you will see Amédèe Lynen; cross the street to the side for the even numbers. The first building is number 4 and the second is number 8. Ring the buzzer of Number 8 two times. Bart, our friendly non-alkie receptionist, will direct you to the AA meeting room which is usually on the 2^nd floor.
