Apart from the classics that everyone's been mentioning - sewer, water and ice levels - desert levels have always managed to find SOME way to bug me. When it's a 3D game they're brown and boring to look at, when it's a 2D game they always seem to have really annoying enemy placement (World 2 of Mario Bros 3 is by far my least favourite). A combination of Tatooine and Taris are the reason I don't re-play KotOR all that often.
These rarely come up anymore, but for old-school FPS I used to hate the train level. If they're done a la GoldenEye (By far the most common) they're just a room copy-pasted over and over, if they're done a la Half Life 1 they're usually a really annoying, slow puzzle.
