In Norway there is a town called Hell, that regulary freezes 30 5, 5:21pm

It can also be mentioned that Hells Angels in Bergen, Norway, have their HQ in an old railroad tunnel/workshop in Helldal. They call their HQ "Angel's Place".

So you could say that their address is:
Hells Angels
Angel's Place
Hell's Valley
Bergen

Although I believe it would be just as efficient to use the proper street address.
