Indeed good airport and nice lounge - great beverage selection (self serve) but very limited food selection. Only magazine store (though probably 99% Spanish) is before security - as is the proper restaurant (called la patria I believe).
Also - rental car return is rather confusing - no signage when entering the aiport. You park you car in the main carpark (anywhere) - go inside where the car rental desks are on the right of the entrance - and the rep will walk back to the car to check it out. If no-one is at the counter wait for the rep to return.
