The word "accurate" in that headline is doing a LOT of work.

Here's how the results were scored:

"Computer evaluations compared the relative proportions of greenery, building and sky between source and generated images, whereas human judges were asked to correctly match one of three generated images to an audio sample."

So this is very impressive and a cool piece of research, but unsurprisingly not recreating the space "accurately" if you assume that means anything more than "has the right amount of sky and buildings and greenery".
