This is the most updated guide of Caracas City. The city is still
unsafe and the political situation is kinda unstable. If I were you, I would keep low profile and leave my expensive stuff in the hotel. There is no reason to be paranoid, however. But you should be very careful and find some local friends. It will be better if you already speak some Spanish.
I encourage you not to take your smartphone in the street. Reach a shopping mall or store instead. And dress like the average Caraquenian. Yes, this is South America. But this is not Hawaii or Margarita, guys!
Caracas is a very interesting city and there is much to do and explore. There are many hidden gems in the city and many locals do not know them. I advise you to meet historians and well-educated Venezuelans. Casa John Boulton, next to the National Pantheon, is one of the most impressive places in Caracas, mostly overlooked by tourists.
You will have a good time.
