All these places are less than 5 blocks from villas. Unfortunately tourists are unaware of this. Expats living in the city really should know where they are. Villas are very diverse, but as much as you can find immigrants, workers, etc they also host dealers and criminals. There is a villa in Puerto Madero ( Rodrigo Bueno ), Recoleta and Plaza San Martin are right next to Villa 31 and San Telmo is right next to Constitucion ( the most dangerous area in the city along with La Boca - Villa 21-24 ). Villa 31 goes all the way from Retiro to well past Law School UBA on Figueroa Alcorta ( almost until Paso Alcorta mall ). It is known by most locals that the area is not good when empty... my own borther was mugged and robbed right there 30 years ago and left barefoot... Be always aware of your surroundings.
