Pardon me, I'm having trouble finding if there is any other housing besides settlements and the house in diamond city?Also what is safe to store items in the entire game(for example do settlements and the house in diamond city fall under this)?

Reason I ask is because in my opinion House Building on PC is hard with my keybindings.

i put stuff on both my main settlement and my house on Diamond city both are safe. Never lose anything. (well one time my companion took my power armor fix it after a while)

So settlements and the house in diamond city are it?

I built a large chest right beside the power armour dock in Sanctuary to store gear. Havent lost anything.

Does Vault 111 have any Safe Containers?
