After School Childcare Needed - Perfect for Gap Year or College Students

We are looking for someone to be home when our two boys (ages 9 and 12) come home from school.  The hours are be 3pm-7pm with a one hour earlier start on Wednesdays.  This would be an ideal position for someone who is in London with their family on a gap year or a college student who is here studying in London.

We live in Maida Vale and the boys come home on the bus.  Both parents work full time and we’re usually home by 6:30.  The boys have various after school activities and playdates and will need help with homework as well.   No driving required.
