Mandarin speaking nanny - 3 afternoons a week

Hello! Looking for a Chinese (Mandarin) speaking nanny to look after our 2 boys - 5 years old and 8 year old after school. Duties are take them to sport/activity, make dinner, play / read with them, get them ready for bed and their laundry once a week. Starting from end-January for 3 afternoons a week. Tuesday to Thursday (from school pick up at 3pm until 7pm or so. On Thursdays will be until 9pm so my husband and I can squeeze in a quick date night!) and occasionally maybe a Monday or Friday afternoon as well if needed. Must be good with love cats (we have one big fluffy one!). We live 5 minute walk from Central station. We have had many au pairs and nannies from Taiwan and China and hoping we can find the amazing next person!
