We spent several days in Lima, also waiting to join up with our tour group. Our focus was in the Miraflores section. Never felt unsafe or threatened as we walked around. Nearby ocean front (at "Loves Park") and strolling around the cafes, stores, etc. at JohnF. Kennedy square while people watching are what we remember most (along with getting real drunk with an Australian couple and a father/son from Denmark.) Don't forget to try the empanadas and the ceviche! about 7 years ago
TravelMom, Peru is not a wealthy country and the divide between haves (tourists) and have-nots (many locals) sadly often leads to high levels of petty crime. It's not a lot worse than many other popular tourist spots, so take all the usual precautions with your belongings and enjoy the amazing city.
here're a few more tips.
