We've just spent 2 amazing in NW Argentina with Angie. In short Angie is awesome. She went well out of her way by driving to La Quiaca to pick us up in the morning, arranged a trip to the extraordinary beautiful Hornocal then an overnight in Purnamarca, followed by a long day's drive to Cafayete and return to Salta to fit in with our condensed schedule when our flights to Iguazu were changed (we certainly wouldn't recommend such a tight visit: 3/4 days should be the minimum).
She's a great guide, safe driver and a wonderfully warm and knowledgeable person. Not only did she inspire us with her love of the region, but we felt as if we really got underneath the skin of the place with all they human interest stories she shared, as well as her take on local politics and economics. She never complained about the truncated programme and allowed us sufficient time to see and photograph this amazing place.
Highly recommended: we'll be back!
