What did you like about it? The airport is not bad, but it's way out of town, tiny place.
It's very dreary. The railway station looks like it's about to collapse and the airport itself makes you feel like you're back in the 80s.
Worst I've seen recently is Berlin Schönefeld.

Smoking is, yes. In Zurich they have those smoking rooms and they work fine. In Warsaw they tried to build something similar and they totally screwed up so you can smell the smoke 200m away.
