Convenient location, buses are served on schedule. And you will leave not only to many cities of Ukraine, but also to EU cities, as well as to Moscow. It is important to have a luggage storage and the cost of one place is 5 hryvnia for a whole working day, which is about 25 rubles. You can have a cheap and tasty snack in the cafe on the second floor. And here's the toilet...quite decent...2 minutes from the bus station. Have a nice trip!
A normal train station in general. Although, as for the regional center (from which buses go to all cities of Ukraine and not only), it would be possible to modernize.
Next to the railway station, it is much cooler and more spacious.
