It has a similar hub-and-spoke layout, but each of the streets are not only more distinct from one another than in Lumiose, but they're also laid out in a line rather than in a big circle, so it's easier for the player to keep track of which road is which. It's less bloated, too; there aren't a dozen cafés and boutiques copy-pasted around the city, each lane only has a handful of enterable buildings, and they're all entirely unique, so every landmark stands out a lot more. All in all, I'd say Castelia is much easier for the player to navigate and do all the business they need to in.
