Alhambra 6b+ has 18 pitches and is 600 m long. And slab climber will love it. For my taste, too much slab climbing and too less face climbing. About 12 pitches slab.
Sometimes the protection was placed weird, a wee bit too high for our size. And somehow we didn't trusted the rock as much as we did yesterday. Maybe if we would have climbed it a the end of the climbing season our view may be differ.
