Native english to play and talk with 2 kids

We are a family of four looking for a native English speaker student to play and talk with the kids of 7 and 11 years old.  The idea is 2 hours per day Monday to Thursday, but we can organice it differently if it suits you better!.  We live in Aravaca, near Moncloa and Pozuelo and can also offer you an individual room with private bathroom if you need it!.
