The airport is normal. It looks small, with short lanes for take-off and landing, but there's plenty of room for everyone. The information is all there. Where to get to the bus without even knowing the languages is easy. Big duty free.
A small regional airport. Walk to the plane. But it's quite spacious. There are several cafes. There are many car rental companies on arrival. There is a large parking lot of these companies nearby. Rent a car very quickly. You can get to the center of Heraklion by taxi, but it is expensive. Near 20 m., bus stop. 2 euros to the center.
