My husband and I have used Go Aupair for several years now. During the last four years we have had 2 Au Pairs. Not because we wanted someone new, but beacuse of the visa extended to our au pairs.
We could not be happier with the program. First, Go Aupair screens us and makes sure that we are a good fit before they do the same with the Au Pair. We have two kids (boy & girl) and we both are working professionals. The peace of mind provided by our wonderful aupair is priceless. She gets them ready in the morning and takes them to pre-school and picks them up afterwards. She lives with us, but we actually spend less with a full time aupair than we would with a nanny or daycare. She even teaches them French :)
We couldn't be happier :)
