The Google maps thing isn't much help, for example, if you can't read the map -- like in Japan, which is filled with coin-op laundries. Also it doesn't work in countries where you don't know what a coin-op laundry is CALLED. It took a lot of searches for me to discover, for example, that they seemed to be called "launderettes" in England, and that's an English-speaking country where it's easier!
