> As to the language: Clean and crisp say both pretty much the same thing in that sentence, crisp is only along for the alliteration (as is cheerful). My Latin teacher would be delighted.

Technically, an alliteration is based on the sound. So while "clean", "crisp" and "client" are an alliteration (beginning with the [k] sound), cheerful (beginning with [tʃ]) isn't part of it.
