Babysitting - some Houskeeping - Drop-off / Pick-up Kids (Au Pair)

We are an international family living in Vienna (Austria). We speak German, English and French at home (I do speak some Greek).
We are looking for an Au Pair that will stay with us about 10 - 12 months from September 2021 (onwards / starting day has some flexibility).
My husband and I work and we have our kids attending child care and school at two different locations. We are hands on parents hence are very much involved with our kids. However we need day to day help with bringing and fetching the kids from school and help us in the afternoon with kids activity. We would also need some help with the household (cooking, cleaning, shopping etc.). I'm estimating about 25 hours per week.

We live in Vienna, which is a beautiful and safe city. We live in the city center and public transport is great to get around. Winter are cold and windy though.

The babysitter/Au Pair will have her own furnished room and also her own bathroom.
It is customary to cover some of the travel expenses and also the costs of the language class. Besides that you have about 4 weeks paid vacation.

Please feel free to contact me if above is of interest.
