Exactly, I once had one for a couple of months midway between my condo and the house I was moving into, because the house wasn't going to be empty until the day I was moving into it.

Before that I had another one to keep things like decorations (like you said), but also all the kids stuff that my older son had grown out of, but the younger hadn't grown into yet (plus seasonal swap outs). Condo living didn't leave a ton of storage.
