The case when the convenience of traffic flows covers the lack of comfort. You can go to all points of Ukraine without any problems and at an affordable price. And this, in my opinion, is the main thing.
It would be good to finalize this bus station (electronic signs with platform numbers, flight schedules, delays. The emphasis should be on the cleanliness of the territory, a cafe with coffee). There is a place to warm up (there would be more places to wait), there is a toilet.
