The views of Rio were fantastic. The driver who picked us up at the hotel was very friendly; however, the ground operators for the helicopter didn't speak to us - simply motioned for us to get on and off of the helicopter, more like herding cattle rather than a personal way to treat visitors. I would have liked to have the option to do this at noon rather than so early in the morning. The online sign-up process and email I received didn't even specify the time of the tour. I had to call Brazil to find that out. This is a key detail that should have been very clear all along.
