a few individuals who express strong negative sentiments about the city.
i got you, bruh! don't listen to Argentines on reddit or on these forums...the locals are very negative sometimes, mostly i think because they have zero perspective, from not being able to travel anywhere they can afford.
that being said, the air quality today was the first time in my 2 months that it was horrible. i couldn't see the Rio from my balcony, so i didn't let my dog outside and i postponed my plans. it shows 78 quality now, but it was around 150 when i woke-up:

that being said, air quality in the Midwest during winter, when people burn wood for heat, is sometimes just as bad. and 150 is common around Northern California or Oregon, or in Canada last year when the whole country was on fire
i don't think there's much good info on air quality in BsAs; it's like there aren't very many sensors for 13 million people, yet in the USA you can find thousands of sensors in any city.
regarding annoying things, there's a separate thread on this forum about that, but many people give complaints that apply to any big city. i would say people in Buenos Aires, locals especially, and the more Italian they look the worse they are at this, will just walk in front of you...cut you off, turn in front of you suddenly, or stop in the middle of the sidewalk, or walk side-by-side so their group won't let anyone pass. it's really annoying and there's a sort of lack of consideration for other people. i just started shoulder-checking people lightly, and sometimes i talk sh*t in English if the affront is especially bad. i was walking up the stairs in my gym and some 40-year-old lady just stopped to talk to a cleaner, blocking the entire upstairs for 30 seconds. i find this happens in BsAs way more than other cities i've been, but i haven't been to Italy yet to know if it's just an italian goofy aspect of their heritage
ask specific questions if you want...i'm from the Midwest USA and i will hook you up. just come here and you'll learn more than anyone can teach you. but 95% of Argentines in these types of sites are commies and will be negative. it's super safe, plenty to do, and you don't have to worry about WorldWar3 or CivilWar2 while you're down here : ) plus things are 25-50% of the cost of the USA depending on how frugal you are.
