What I find to be elegant in a codebase is where the chosen abstractions or seams that separate subdomains/concerns is well chosen that each is handled mostly in one place without a lot of ceremony or machinery. I would call these 'well factored' for factors which are domain-specific.

Each language has different ways that may lend itself as part of this shaping, but I like being able to think of this as something to look for when reading and strive for when writing, irrespective of the language at-hand.
