If you're coming to Santiago for a two week vacation, this is not the place to stay. Pay more and stay closer to the Constanera Center in Santiago. More is open, available and convenient.
If you are coming for an extended stay in Santiago, this apartment is a good choice. Near two subway lines, nice building, security, etc.
Things in this neighborhood don't open until noon and close around 5:00. But like I said, if you have a work assignment in the city, this is an affordable choice in a nice building.
