Are the guild chests in the Cistern safe to store loot that I want to keep?

Funny, I could have sworn I posted this topic yesterday but I couldn't find it, not even using search or checking my account for posts and topics...

Probably. I think there might be a specific one for your character, but I don't know since I have a house in Riften that I use for storage instead.

guild chest is a safe chest i used it but i finished the Dark Brotherhood and i liked that a lot better so i overweight transfered all my stuff there
