The owner was attentive and really loves what he was doing. The environment was positive and instruction / assistance very good. My girls loved it. The only reason I did not write a 10 is because there were a few assistants who were less helpful. I wish the hours were more flexible during the week and on Friday, although that is the schedule that works for 95% of the parents / kids.
