International Schools in Madrid ( For Children 3 and 7 years )

My recommendations for international primary/lower schools in Madrid? My children will be 3 and 7 upon our arrival. Thanks!!

My wife worked at Kensington in Pozuelo years ago and she thought it was excellent

The most famous international houses in Madrid are these:
1- International College of Spain
2- Runnymede
3- King's College

But I don't personally know any.
