ENGLISH SPEAKING NANNY - pick up kids at school

Hi! We are looking for a nanny to pick up our kids (2 boys, 6 and 9 years old) at school (French Lycee, metro Esperanza) and play with them, from Monday to Thursday (17-19 aprox, pending on final school agenda). We live in the Goya metro (same Line). Nice, happy and well educated kids.
