Apartment needed in Santiago for 1 month

Finding an apartment to rent in Santiago is, at least for me, a pain in the butt. But I have no choice, so here goes.

We're a couple searching for an apartment in Santiago. It should be fully-furnished with an A/C in the bedroom. We have a car, so transportation is not a problem.

Regarding budget: we don't want to spend $300/week.

Any help is appreciated.

Thanks.

we prefer something within a reasonable distance from the center of Santiago. We don't need parking, we can just park on the street.

We're just looking for something safe in a decent neighborhood at a decent price. And A/C in the bedroom.
