There are good and bad things here. To understand the bad things, you have to understand what it means to be "vivo". Too many people here, but certainly not all of them see this life style as an ideal.
Some anecdotes:
Whatever you lose out of sight for a moment has a high chance of disappearing, even if it is not valuable. I have had my old walking shoes (that I would not wear at home anymore, only here) stolen while I was dancing. They have stolen my shoe bag with nothing in it (probably assuming it might have contained something) and my glasses of more than 10 years old. I once met a tourist who put his laptop under his seat and once he wanted to take it back... it was gone. As a general rule, do not carry valuables with you when you go out, keep your money in your pocket and only as much as you need.
When I lived here with my ex-girlfriend, the Internet from Telecentro stopped working. After 2 weeks with repeated calls from our side, they still did not care to come and fix it, though they happily kept sending us the bill to pay. Here you get customer service when you buy something, after that you should not expect it anymore. We switched to Fibertel and the guy who fixed the cable asked the phone number of my ex-girlfriend (behind my back) and started texting her to date with her.
If there is a garbage can at 5 meters from you, why should you make the effort to walk there and not just throw your garbage on the ground? Crosswalks here mean give way to cars... You may enjoy listening to the dogs from the neighbourhood barking any time of the day.
If you can live with the kind of negligence I am describing, Buenos Aires will be great
