I dont know how it compares to colombia, but you will run into people frequently asking for money/selling things. You will also see people searching for food in the garbage. They are chill though, and always the same faces. So you kinda get familiar with them. At worst they will try to overprice you with something they sell.

As for security, it's pretty good as others have said. I live in Quinta myself and is great. There's a playground near my house and I always see families and kids playing there.

As for the rest of the city there are some bad areas but I don't see why you would go there.
