excellent
I have found Sofia's profile via this website. She had got good reviews and great credentials. I haven't had a babysitter for a while, but urgently needed one for my 6 year-old son.
Sofia came across as easy-going, yet professional person. My son liked her straight away, even if before he was upset he is staying at home with someone he didn't know. As soon as they met, all bad mood gone away and they played very well.
I have recommended Sofia to all my friends, and very happy we now have a reliable babysitter we can trust.
