HostMom Pippa takes advantage of easy online tools, and comes up with *surely* one of the greatest ideas for helping your au pair visualize her/his new surroundings (aka your world).
She recommends creating a Custom Google Map:
An easy way to share information with your incoming AP before he or she arrives is to create a custom Google map. You can add pins for your house, the kids’ schools, after school activity locations, cafés, recreation centers, Costco, Starbucks, parent workplaces, restaurants, etc, many of which can include links to websites associated with those locations.
Many locations have pictures already associated with the maps. In addition to visualizing the spaces, the AP can also get a sense of distance and direction of frequently visited locations (or appreciate just how long your commute really is!) Through control of share settings, the map may be as public or private as you wish.
