Buenos Aires is a modern, sophisticated city, and women travelers – even those traveling alone – should not encounter many difficulties.
A few men feel the need to comment on a woman’s attractiveness. This often happens when a woman is walking alone; it will never occur when she is with another man. Comments usually include whistles or piropos (catcalls), which many Argentine males consider the art of complimenting a woman. Piropos are often vulgar, although some can be eloquent. The best thing to do is completely ignore the comments. After all, many porteñas are used to getting these ‘compliments,' and most men don’t necessarily mean to be insulting.
On the plus side of machismo, men will hold a door open for you and let you enter first, including getting on buses.
