If you can get someone to walk her, then that's great! But be realistic. Besides working, add sleeping - you won't be giving her much of a life. And if she's bored, she may get destructive. And if she's not let outside, there's the house soiling to consider. The only reason I'm spelling it all out like this is because my very first GSD came into my life under the exact same circumstances. After keeping his puppy confined in an apartment for so long, the original owner couldn't take it anymore and rehomed him to me. He loved his dog, but eventually came to the conclusion that he really shouldn't keep him anymore. I loved him very much too.
