A great area; it's located nearby brakfast places and there's a supermarket 2 minutes walking; the subway is pretty close and there's 24 hours security at the reception.
The apartment has a great size, the bed is really comfortable, the sunset is stunning from the window and there's a closet to put your stuff which I found pretty good.
You have to buy your onw toilet paper, soap and potable water because it wasn't offered, at least during my stay it wasn't. If is your first time in Chile, would be good bringing plastic bags, because for garbage there wasn't any at the place (and they don't really give plastic bags in Chile - it's cultural).
