I flew with Ryanair into this airport a few years ago. The approach is great, passing around 800ft over the hills and doing steep turn over the castle into land.
The runway is short and I also experienced a firm touch-down, as you don't really have room to "float" on this runway. The a/c did flare slightly, but you can't really afford to remain airborne for too long. It's best to use the maximum length of runway available in places like this; that's what I'd do anyhow. If you want a smooth landing, go to an airport that has a longer runway.
It was one of the best landings/approaches I've had yet. I believe I heard only Captains can fly this approach.
