Thanks for sharing your story in the cash is king land of Argentina.
If only you could convince the rental properties to take pesos, that would really be a game changer.
But I thought that cuevas were giving rates much higher than what you were getting on your trip but maybe I am wrong.
A good resource for this type of info would also be BAEXPATS.ORG. They can be a bit rough around the edges but its a great site for all the info on traveling to Buenos Aires and the rest of Argentina.
