It is 13 days of daylight. The astronauts and their spacecraft were okay in the Sun, not to mention solar powered Rovers that operated in the sunlight.
That’s true, but maintenance of a more permanent structure would have to require a high degree of self sufficiency, and the expense to withstand the higher daytime moon temperatures could be prohibitive (what was experienced in space flight was extremely low temperatures, down as far as –454°F).
A station at either of the lunar poles would not suffer from the 13 day day / 13 day night problem.
