If you come to Buenos Aires to spend some days, weeks, or even months you will find some cultural differences in the bigger picture. But as well you will face interesting, annoying, and funny things in everyday life that are way different from what we are used to at home. Travelling is all about that! I'll describe an unsorted mix of some of the most interesting things which might be of use for the tango traveler.
Buenos Aires is a huge city, and since the surrounding county is named Buenos Aires as well, people here distinguish the City of Buenos Aires and the Provincia de Buenos Aires. The city is mostly named "capital federal" or just "capital" versus "provincia" (de Buenos Aires). It is important in some points of transport (in capital you have taxis going on the streets and you can just stop one by your hand sign (for more transportation info see
here), while in provincia you have to call a remise to get car transport), telephone numbers, and slightly higher prices on colectivos.
