The airport is large and spacious. It's nice to see: palm trees, fountains and just pretty shops. However, most of the staff barely speaks English and it delays. We took a ride on the subway there without a driver, not everywhere, but especially at the airport, you will see this.
If you are flying in transit and the transfer is small, two hours, then I recommend acting quickly, since the terminal is incredibly large, but there is everything you need, even a shower, but without towels
