Student Desk Integrated Montessori School in mercedes, pasig - any feedback?

I'm a big fan of the Montessori approach though I haven't heard about this school. Wondering why they don't have a proper website, and here they mention that they have a small class size but it's 10-15 kids per classroom -- isn't that a little big (for nursery at least)? https://studentdeskims.wordpress.com/benefits/
