A medieval castle in spain. There are tons the ones well restored has all anti zombie measures no way in stone walls water and places to cultivate and maintain animals and water wells. they survive centuries when my country had a war each year 800 years of reconquist . Also secrets passages to outside you could use and defend easily. Sadly there is no castles in america that’s why dont appear in films 
I would probably stay in my secret underground biological testing lab which couldn’t have possibly accidently started the apocalypse…
@Doctor does your underground lab happen to have the name: The Hive?

My list of (totally) possible outcomes that I would have in the zombie Apocalypse:
-I utterly fail, and would become one of the first zombies
-my top secret moon base more than likely made the zombies worse
-I end up hiding in a alley only wearing rags
-I scream every time there is a zombie while the cool and macho survivors kill them
-I become the leader of my disgruntled group, and bring them to paradise
-I set fire to everything I see because I go completely insane
-I destroy the world by hacking into the worlds nukes, and firing them
-I build a underground network of tunnels that are (completely) safe
-I create a island from scratch to hide from the zombies
-I create a cure for the plague, and save all of humanity
-and the most (completely) realistic of all… drum roll please…I kill every single zombie with my pure charisma, awsomeness, machoness, greatness, and handsomeness. Then I become the most (completely) fair leader of the world, and would live forever with the elixir I made, and live in luxury for the rest of my endlessly blissful reign. Also creating world peace forever because my rule is so great.
@Porter, my real name is Wesker
