We had 36 hours in BA before touring Patagonia and then came back to BA for a week at the end. Mariela arranged for us to be met at the Airport and the next day took us on a tour of BA, which introduced us to the sights, manners. tempo and culture of BA. This gave us both a historical and a comtemporary insight into the city and its attractions and allowed us to plan for and to use our longer stay in BA more effectively. We have never useda service like this before but we would now recommend it as a rapid way to come to grips with a foreign city on your first visit.
