We offered ours at one time, and we had an older lady, she was very very nice and even stayed on with us for a month after the convention going out in service and was such a help around the house, cooked, ironed constantly cleaned, she was a pleasure to have, we had her back the following year and she had another sister with her from Oregon who happened to be in the area when the Dc was on, She too was a pleasure to have around, they wanted to do all the household chores but we said no, the children have their assigned jobs and we want them to still do it. They were excellent cooks and again both stayed for about 6 weeks after the Dc. We kept in touch with them, and still see the lady from oregon once in awhile.
Sou our experience was good with that arrangement.
