Well this was a bunker to survive a nuclear attack so we'd still have military command...so I imagine pretty F'ing bad. There's was an AF base where he was based out of not that far away. Where he would have slept if he didn't have an apt off base. He only worked in the bunker. You'd enter and leave by cover of darkness. A few hundred service people from USA/NATO worked there. That book is actually a good glimpse of what it was like.

It’s about 45 mins drive NW of there by Birkenfeld.

My dad served in the Börfink Bunker. At the time in the mid-late 60s it served as the NATO command center for Europe. Essentially the spear tip of our response to any Russian threats. There’s a good, easy-read book about it…no connection to my dad or me but I’ve read it. Linky: https://www.amazon.com/Two-Years-Watch-Learned-Secret-ebook/dp/B079KVBQCM
