Great tour! Rodrigo was very knowledgeable and provided us with a lot of information, and was able to answer any question we had. I've learnt so much about Argentina and it's history, and I know understand the Argentina people a tad better. My only complaint is that the tour took 3h and 40 minutes, instead of the advertised 3h, but time really flew by.
I did appreciate the tour. Giovanni did a great job explaining the history of Panama, which was interesting. Sometimes however I felt that there was a bit of upselling to various restaurants and such. This I don't think need to be part of the tour. Also the advertised duration of 2h 15m was overdue by more than an hour, which affected my planning. Reversing time, I would do the tour again.
