This airport was my first European airport that I've ever been to. Usually I get the window seat but this time I got the aisle, so I can't comment on the size of the airport.
We flew United Airlines operated by (French - Air Canada). The landing was smooth and we were able to find a gate right away to depart from the plane. As you walk away towards the baggage area from the plane, you come to a tube station that offers to stations. One for baggage claim and the other for a connecting flight.
Our train arrived promptly and the ride to the main airport was very smooth. Walked from the tube to the baggage claim was stress free with easy to find signage to our prompt locations. From my experience, the airport is very modern compared to LAX in Los Angeles. I wish a lot of airports were like this (Honolulu International Airport). Overall it was easy to get around and it was very clean and up to date. But I assume that's how most EU airports are like.
