Hi
Live in N4, heard St Mark's Nursery on Moray Road is great and has really improved since big staff changes, is anyone out there been there, going there or know of it?
thanks! ds 3 1/2 and they seem to be the only one around with spaces at the moment. I was worried that spaces meant it might not be very good but apparently they've just increased their capacity by doubling the no. of sessions they offer so I guess that's ok.
