The only review I found was an old one on the Spoon...which shows the depths to which I will sink to try and help our members.
The review was definitely not good...the usual litany of broken promises and general mistreatment. A few others, including what appears to be our own Babala, indicated they had heard good things about them...at least 2-3 years ago.
Hard to call things like this. The school seems to be old and well-established. I'd take the fact that the internet isn't swarming with the aneurysms of abused former teachers to be a guardedly positive sign.
