We took the Metro from POP to Santiago in early July. The bus is air conditioned and has comfortable seating. Plenty worth the price. Use the bathroom before you get on the bus. It's doable, but no AC and bumpy. The trip is about an hour. The schedule is pretty much on time. The views are beautiful. Some people sleep. The Santiago bus stop is pretty nice. Close to where I lived and went to school many years ago.

Has shopping across the street. Baskin Robbins, KFC, Burger King and McDonald's within eye sight.
