A couple I know will travel from Greece to San Francisco for their honeymoon, and then visit other places too; it's their first trip abroad.
I remember when I first came to SF, I used Google Maps to navigate. Once I was on foot, and it guided me directly into a "bad"/dangerous neighborhood. I was afraid that if I turned the other way I came from, they might be offended and react. I made it through safely, but the images I saw were shocking and hard to forget.
How can I advise the young couple to use Google Maps to boost the chances of avoiding this experience? Maybe use Apple Maps? Or it won't make any difference?
PS: I'm not in US now to check myself.
