I took my daughter to a trial class there a few months ago. The teacher was great -- she kept the little ones busy and engaged them in a very positive way. My daughter enjoyed the class a lot.
On the downside, I noticed that of the 15 kids that were in the class, there were 5 that were visibly sick (runny nose, coughing, etc.). I was surprised these kids were allowed to stay in the class the whole time (I've been to other playgroups where the policy for sick kids is implemented more strictly). Unfortunately, my daughter got ill the day after attending the class, and I can't help but think she must have caught the cold from going to the school!
