When I did get in I got the airport van, which takes you to your door, and just told him one of the addresses in the lonely planet. Well, there turns out to not be hostel there anymore, so the driver insisted on taking me to another place. That place was full. SO, he insisted on taking me to another place (all the while a girl waited patently to be dropped off herself). At the third place there was room, but as soon as I went in to check the driver split with my stuff. After a half an hour or so and time on the phone with the company he returned. So, all is well that ends well I guess.
Good to be in Santiago!
