Is Partido de San Fernando safe for solo female travelers?

It’s safe. The public transport here is safe, as well. It’s all about walking in areas where there are more people and in comercial areas. I would say that, as a woman, I would not walk alone at night but because I tend to take my precautions. But if you have to go somewhere at night, there’s no problem. In Argentina, arms are illegal. So, it’s weird that if someone robs you, they will use a knife. People in Argentina are very friendly, if you ever find yourself in trouble, there will be people that will offer themselves to help you.
