Lunar south pole
As the moon orbits, it keeps one face always opposite the Earth. So when the Sun shines on it, it shines obliquely on the poles. Thus it never reaches the ice inside the craters, and the water stays frozen. The same pattern might apply to the Moon's northern pole, but that has fewer craters.
