I am not putting my son as a commodity, and like I said I want to stay for few years thats why looking for something which has dual language would be very good, not for me but for the kids.

International scchool are a bit expensive especially if you have 2 kids, so I prefer some private school which are taughting 2 language

Either polish or English will do. I want to settle for few years in Krakow so I guess learning polish would be a good idea.

Could you let me know the address of the school?
