Live-in nanny / au pair

We are looking for a live-in nanny or au pair to look after our two children (our son is 7 and our daughter 3) after school and during the school holidays. Our children speak both Greek and English and we would love them to continue to learn Greek. The working hours will be 3-6:30pm Monday to Friday during school terms and 8-6:30pm Monday to Friday during the school holidays, with occasional babysitting (1-2 nights per week). The duties will involve picking them up after school, preparing their evening meal, reading and playing with them. No housekeeping duties will be required other than helping with their laundry.
