We spent almost all the time before departure in the IgA Lounge.
An extremely comfortable business lounge, spacious, lots of "air", an open layout with a view of the airport - you can safely watch the hurrying passengers. The only drawback: the business is closer to terminal A, so if you have a flight to Russia, then most likely it will be Terminal E, which means you will have to spend 20 minutes (!) to move from the hall to your gate, because the airport building is really gigantic!!
A huge airport, an aviation hub, is conveniently arranged, everything is clear, the distances are long, you need to put in more time to get to the gate.
