english speaking native

We need someone reliable to take care of our 3 children during the school year from 1 pm to 3 pm: picking them up from school, having lunch with them, playing games and teaching them English in a funny way. At 3 they have to go back to school, which is 10 minutes walk from home, we live in Majadahonda, a well connected area 15 minutes from Madrid. . The  kids are 7, 9 and 11 years old, we found last year a girl through Erasmusu and it was a great experience!
