My children attend Mantua. When we were moving into the area a few years ago, it was one of three schools we had on our short list though not necessarily our first choice. We ended up finding a house we loved (and nothing we liked in the other neighborhoods--it was a really tight market) so that's where we ended up.
We've been very pleased with the school overall. Our kids range the gamut in academic skills from AAP to some SN, and we feel that the administration tries very very hard to accommodate their different needs. Overall, the teachers have been great, with the exception of some in 4th grade, which seems to be a bit of the weak link at the school. The environment is very inclusive and welcoming and the neighborhood is very family oriented with a moms' group, community pool, etc.
As a PP posted, the PTA has a very good relationship with the administration. When we moved in, we initially thought the extra-curriculars weren't all that well rounded but in the past two years a lot of new programs have been implemented (for some reason, the PTA website is a bit outdated and only lists a fraction of what's available). They vary a bit from year to year but for instance this year, in addition to what's on the website, we also had off the top of my head:
Odyssey of the Mind
Destination Imagination
Chess
Lego Robotics
various arts and crafts classes
Science Olympiad
and probably others which I forget.
