My sister and brother-in-law, who live in Barcelona, are looking for a native English speaker to be with their children two afternoons per week (Tuesday and Thursday). They are a Catalan couple with three children -aged 3, 6 and 9- and they live next to Plaça Espanya. They are looking for someone to help the mother to pick the kids up after school (at 5 pm), take them to after-school activities or to the park, bring them back home and stay with them until 8 pm. It wouldn't mean being with the three kids alone but rather help the mother during those three hours while speaking in English to them.
If you are interested please contact my sister Begoña by sending an email to Protected content . I can certainly say they are a great family :)
