Going on a trip with Eduardo should be mandatory for all visiting Argentina. What a wonderfull person, and what a wonderfull experience!
He will take care of you like you are family, and we've learnt a ton about Argentina.
The camper is rough as nails, but accomodated with all the creature comforts needed for a very comforatable trip. The iconic "collectivo" will guarantee a ton of meet ups with people on the road. Leading to a lot of invitations, leading to the most extraordinary (local) experiences.

Can't recommend enough!
