ELI5: Why did USSR allow for Austrian reunification but not German?

Both Germany and Austria were divided into four occupation zones following World War II, and Vienna was divided like Berlin. So why was there an East Germany and a Berlin Wall for so long but there was never an East Austria and a Vienna Wall?

Austria was willing to sign an agreement that said it could never enter a military alliance with either side. This satisfied both the USSR and America and to this day Austria is just as neutral as Sweden. 

Germany was not given this option.
