It's a well-developed urban area with reliable public transportation and many public spaces that are well-lit and busy throughout the day and night. However, like any location, it's important for travelers to stay vigilant, particularly when in areas with less traffic or during late-night hours, and to use common-sense precautions, such as not displaying expensive possessions openly.
