It depends on the car. Each host sets their main pick-up point and can add extra ones —airports, bus terminals, ports— or deliver within a radius they define themselves.

On the car's page, before you book, you'll see the available pick-up points with their price. If the host turned on a delivery radius, you can ask for an exact address within that radius.

When you book, the pick-up and return screen shows the host's own point —the origin, always free—, the delivery locations they offer with their price —for example, «Aeroparque Jorge Newbery (AEP), +$25,000 ARS, free for trips of 2+ days»— and, if they turned it on, custom delivery at an address you choose. The screenshot is from Argentina.

The host decides: it can be a fixed price per delivery, free, or free from a certain number of rental days. The cost appears in the payment summary, in the trip details and on the booking card.

In Argentina: Aeroparque, Ezeiza Airport and the Buquebus terminal.

The point you choose is tied to the trip and both sides can see it, so there's no need to coordinate it again over chat.
