french course for US au-pair

Hi all,

we will be relocating to Tervuren in a few weeks and have an au-pair girl lined up to join us. She is keen on learning French, which of course is also part of the au-pair package.
Ideally she would meet other au-pairs, too, so she can build herself a social life.

Anyone who could recommend a french language course not too far out from Tervuren, and with other au-pairs?

Thanks for your input
