Hi,I registered my younger boy for their holiday program in Nov/Dec last year and I must say that he enjoyed himself thoroughly during the 3 week duration.First of all, the center is very cosy as it is nestled in the Bukit Timah hill reserves. Secondly, the class size is small and the teacher was able to give a lot of attention to the children. Lastly, I found the program to be very interesting as my boy was able to bake his own cookies and even brought home a self-made paper volcano structure.I would definitely recommend Stelios Montessori to parents.
