I was wondering if anyone could give first hand knowledge on any of these schools, pls?

colegio europeo de Madrid

The International Colegio SEK Ciudalcampo (Madrid)

My son is 12 and my daughter is 9.  They are both currently studying the IB program and speak English but no Spanish.

I would really like them to continue with the IB but am open to all options, money being the key factor in all of this.

Best regards

Adrian
