Schools in athens (Athens)

Hi!
I am a australian and my husband is Greek. We are currently expats abroad and may be moving to Greece in the near future. Our area of interest are glyfada and surrounding areas.
We have 2 children that are currently in British curriculum. I have looked at threads upon threads on schooling and cannot seem to find anyone with a child at st Laurence college in vari. Is there anyone that can give me some information on the school? We love the area so it would be great for us but also we have heard amazing things about st Catherine's and also acs which means we would be changing to American curriculum which is ok.
TIA
Jess
