Have your daughter use the "Find It Guide" which can be Googled -- "Kaiserslautern American find It Guide". There are several reputable companies there....
FYSA - auto work in Germany, especially if her car is American or Japan, is VERY expensive.
The locals in Germany know both the TLA rates and the Per Diem rates -- you get what you pay for. Don't expect to find anything *under* the rate -- as they will charge exactly the local TLA rate.
When I was stationed there, we stayed in TLA on base for about 2 weeks -- wasn't bad -- and if I go back, would stay there again.
