Marta, busca niñera en Bilbao

We are a Spanish couple. We have two twin girls who are almost 5 years old.
We live now in Switzerland, but at the end of August we return to SPAIN, to BILBAO, in the north. We are going to live in a very nice district of Bilbao, Begoña, very close to the center (15 min walking), close to bus and metro stops.
We have had au pairs in Switzerland (from Germany and from Czech Republic) and we have been very happy with the experience. You can talk with them if you wish.
We are looking for a girl as an au pair (external or living in) or a baby sitter, whose MOTHER THONGUE IS ENGLISH. Naturally, at home we speak Spanish, as we are from Spain. We speak English, German and Italian as well.
We need she starts next September and stays with us 3-12 months.
We expect this girl to work a minumum of 16 hours per week to work Monday to Thursday or Friday.
She has not to clean because an external lady is going to do it.
The time with the girls will be take them and pick up them from School (10 min walk), and play and talk to the girls, while their parents are working.
The girls are going to go to school from 9:30 to 14:00, they are going to have lunch at school. They love to play, go outside, read stories, talk, sing, dance, swim, ride on bikes ...
No formal classes are required, you should simply speak and interact with them in English only.
