This is a great question. The best answer that can be given is to choose a place where there is the least amount of traffic in that area. The fewer people that have access to be able to see your safe makes it less likely that anyone will know it’s there. Some people like to get clever and install their safe in the living room behind a painting. They think if no one will see it then they have hidden it well. That may be true, but you are also opening the opportunity for more people to discover that you have it safe. Choose a spot where less people can stumble upon it.
