We used Julie for emergency cover when my other nanny was away. In disagreement with the previous review I found her to be extremely reliable. Once we had confirmed all the details she visited us and met the children a few days before the job started.
Following this, she arrived early at our house to wait until nursery pickup time to ensure she was always on time, as she was travelling by public transport.
The children were happy with their time with her, and each day I walked in from work to a clean and tidy kitchen!
I would recommend her to anyone, and would use her again in a flash (unfortunately she is looking for more hours than we need on a regular basis).
