From the point of view of logistics, everything is clear. Free Wi-Fi, you don't need to register to use it. SIM cards are issued at passport control. There is a subway right at the airport.
It's a great airport.. the main thing is that the luggage can be checked in at least five hours before takeoff..and they are passed with water , food and creams ..
Terminal 2 is crowded, the cafe is small, the toilet is queued and dirty. Perhaps other terminals are better, but Terminal 2 does not correspond to the city.
