Modern airport with free wifi and a Yandex taxi ordering desk.Great for getting a good price for a taxi into the city. Not sure if one can speak English there, as I've not tried to, except when passport control speaks it with me. If you fly there from Yerevan, you can skip customs. Just make sure you save your ticket stub from your boarding pass so you can show it when required.
I set 5 stars, but four in mind. Quite small but not so comfortable airport. All the checks are quite fast, no long queues. Duty free shop is tiny. No discount for children in the business halls (WHY?). Idiotic location of boarding desks far inside the long tight corridors. And the physical absence of priority boarding. Are you the priority passenger? Go and explain it BY YOURSELF to all these people in the corridor.
Love the size of this airport, there is no chance of getting lost there are signs in English so quite tourist friendly. Bathrooms are somewhat clean I do enjoy the fact that there is paper towels to dry your hands.
