There is no point of being an Au Pair without nice hosts, likeable food, transportation, cellphone, friends. If HP don't want or can't provide this they are creating picture of very stingy citizens. Au pair shouldn't go there to struggle.
As a HM, I do not think it my responsibility to find friends for AP. And I think "friends" are the most important item on that list. AP needs to be proactive about finding and making friends.
As someone who has lived overseas twice, APs need to expect some "struggle". Its hard to move, integrate, navigate new systems. You are going to have some struggles. To think you are going to show up on HF doorstep and have a red carpet rolled out before you with everything you want/need/desire perfectly in place is just simply not going to happen. I think this is the problem for many young adults these days...a "struggle" is not expected and immediately the fault of anyone immediately in the path of the struggle.
