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!!
Great gym! You can have a very good rest after a long flight before the next flight. A good selection of food and drinks. There is a playroom for children.
