I have been down here for about ten months. I grew up being bilingual due to one parent being from Venezuela. After visiting Venezuela several times and growing up with that cultre, I was in total shock coming to Buenos Aires. I expected a warm, friendly, sounds weird to say, but Latino culture. That's not what I found in Capital.
First I will point out that there is a HUGE difference between Porteños and the rest of the Argentinos. In my option the majority of Porteños are rude, apathetic, unkind, etc. to outsiders. Within their family, friends, lovers, they are different. However, as I do not fall into any of these catgetories, I feel it is very hard to truly befriend a Porteño. I have actually heard some Porteños say that they don't need new friends because they already have them. People will run into you on the street, push by you on the subte or bus, without even a thought. I ALWAYS say "permiso". I am not a fan of Porteños at all & I have found that almost every other Argentino (non-porteño) feels the same way.
The rest of Arentinos are a different story. One of my best friends is from Corrientes and she is one of the nicest people I've ever met!! I also have made really good friends from Provincia de Bs As, La Plata, Entre Rios, just to name a few places. I have also traveled around a lot of Argentina and everywhere that I go the people are nice, caring, helpful, etc. Out of all my travels, I would have to say that the Salteños win for being the nicest. They were absolute sweethearts & it was a pleasure to be among them.
All my opinions aside, I would definitely recommend still coming. Several people have shared their thoughts so you know what you are getting into. It will still be an amazing experience regardless and I'm sure you will find some lovable Argentinos throughout your time. Although, I can almost guarantee if you meet a random Argentine who is really nice, they are not from capital
