Hi, I'm new to this site and hoping someone could give me suggestions. We're traveling from the US with three little kids, ages 7, 6, and 4. We'd love a nanny who could live-in with us and help with the kids and be present during evenings when they're asleep. Dates are July 4-July 15, located in San Telmo. Some English would be essential. Any suggestions or referrals would be so helpful. Thanks in advance.
