My sons went there last year. The reason we changed is because we have since moved and its far away from us.
I liked it personally. The principal took time to talk with us and even play with our baby everytime we went there!
Of course you will have to deal with the boys who use bad language but that is everywhere. My sons liked it there.
Im not aware of a overly high turnover rate.
Its different here though some expats cant handle this place!
