Ecole Jeanine Manuel in Lille

Hello, we are moving in the summer to Lille with a 13 year old boy, who went to international schools his whole life, in several places. He is an excellent student and in grade 8 now.
I made some research and I think there is only 1 real international school in Lille - Ecole Jeanine Manuel - is that correct?
I would like to receive some more info about this school from parents who have their children there - also with regards to the teaching language and the IB diploma. We would like to choose the right school for our boy. Thank you so much !
