I live in Heidelberg. The apartments and houses (I'm not sure which will apply to you, it depends on rank) on post have built-in closets and that has been enough for us. We also have out own storage room in the basement that we can lock in addition to a common storage room that the building coordinator holds the key to. The housing here is not the best, but you can make the apartments look very nice with your furnishings, paintings, curtains, etc. The walls here are a pain because they are concrete so you have to have anchors and it's best to pre-drill any holes you might need. Off post housing usually does not have built-in closets, some land-lords provice armoire's, but not all of them do and if you live off-post you might have to purchase your own to store your clothing and other things you want out of sight.
