Enormous airport. Depending on the airlines and flight you will arrive and departure on different terminals. I strongly recommend if possible, staying at one of the nearby hotels a day before travelling, Ibis is pretty good.

Incredibly crowded, specially if you travel on the economy class of Iberia. And yes, you are probably going to have a hard time if you don't speak spanish. Still, insist if you need any sort of help, sometimes there are fellow travellers that might help you with that!
