Elementary school in Mexico City.

Hi everyone,
We are moving to Mexico City from Athens Greece in about 2 weeks. I thought we found a good school for our daughter (Westhill Institute), but recently I found few pretty bad reviews of this school, it looks like the curriculum level is very low there and the children are not well behaved. We started searching very late, as we really didn't expect to move to Mexico. So the only available school was Westhill!!!
Please tell me your opinion about this school.
