Code which reads as close to a human language as possible. I mean it on all the levels: from syntax used, naming convention and alignment all the way to algorithms used, quality of comments and complexity of distribution of code between modules.

Simplest example for naming convention:

if (filename.contains("blah"))

versus

if (S_OK == strFN.find(0, "blah"))

Part of it depends on the environment/APIs used, but most of it is of course the responsibility of the developer

Point-free Haskell code. (Not really, though.)

Code in which the different modules or classes have clearly defined contracts, is a good start.

Code which doesn't break in multiple places when you make a single, seemingly insignificant change. It is also easy to follow the control path of the program.

Reusable code is also important. So not only important is the quality of the code, but where do you put. Example, business logic into a Controller is a useless code
