Buenos Aires is right to be cited among the most beautiful cities in the world: wide avenues, parks, cafés, book stores, the warm people made of mostly Italian and Spanish immigrants with a peculiar Spanish like the sound of a different melody, the tango clubs, its Parisian architecture, the most delicious steak in the world, lots of cultural activities that are free to visit; it is a city that you can walk for hours and stop at corner side cafés and watch the people, then walk again with a huge smile on your face.
If you are arriving by an international flight you will arrive at the EZE airport, which is quite far from the centre (about fifty kilometres). The taxi would cost you around forty usd, you will probably will not have pesos so you can book a little more expensive option, the private taxi companies at the airport and pay with your credit card. The other airport at the centre is Aeroparque and it’s about fifteen minutes taxi drive from the centre, so if you have domestic flights (like Iguazu, Bariloche, Patagonia) or travel to closer cities such as Santiago or else prefer this airport as it will save you time and money.
For accommodation I would recommend you to stay at the center, the area around Florida, Maipu, Suipacha, which is lively and close to many attractions. You will need a couple of days to get to know the city: visit the museums (Fine Arts Museum, Malba, etc.), the Recoleta area, San Telmo on a Sunday with its antique shops, Puerto Madero or Palermo Soho at night to hang out at the restaurants and bars, La Boca if you look for a more tourist option. You may buy a night tour to watch tango or go to a local club to watch ‘porteños’ dance tango.
The parrillas are everywhere, they are typical restaurants where you find grilled steak, they are huge and not expensive. At the north of the city you will find organised graffiti tours if you are interested in street art. The 4th of November is Museums night and most of the museums are open till three a.m if you are into arts and culture. Do not forget that that there are many Palermos in Buenos Aires, Palermo Hollywood, Palermo Soho, Palermo Chico…
And finally if you speak Spanish it is great but you will need to adapt to the different melody and tonation as well as different pronunciation of certain letters. I love you Buenos Aires!
