Guatemala City has rather alarming rate of crime in some areas. Stay out of trouble by using plenty of common sense. In Zone 1, after dark, walk directly to places you want to go and know where you are going. In the Zona Viva Zone 10, follow normal precautions anytime, including after dark. Don't get drunk in any of the nightclubs and then stagger back to your hotel. THAT could attract a would be robber there.
