Where to Live among other expats.

I'm relocating to Mexico City. I have 2 young children and they love sports and don't speak spanish. What are the best developments to live in or near Santa Fe, one with lots of ex-pats? Thank you!

Polanco and Bosques de Chapultepec are two areas relatively close to Santa Fe and with high numbers of expats from around the world.  Both are pricey areas.

Thank you!
