Luxembourg has been dubbed the “safest nation in the world” in many polls; as long as you take the normal measures, you should be OK. The area surrounding the train station in the city center is a bit sketchy; you’ll see individuals panhandling. In this neighborhood, there are also some shady nightclubs that tourists should avoid.
Luxembourg’s food and tap water supplies are excellent, and the country’s healthcare system is world-class. Even though the summers may be scorching, the temperature is generally pleasant. These temperatures, however, seldom exceed 30°C.
