It can be, just avoid a few things. Dont take taxis in Managua. They will kidnap you and drop you off somewhere remote and the taxi drivers friend will be waiting for you to rob you. This happened to my buddy and his girlfriend. Also dont hike in the back country. Other than that just use common sense and you will be fine. Oh yeah and dont stay at the Green Surf Lodge in El Transito, unless you want to get robbed that is.
