It's cool that there is a post office right at the station, it is very convenient to use the services while waiting for a flight. It works seven days a week, which is an additional plus.
Mail is normal. But! We ran all over the station looking for her. The inscriptions lead nowhere. If you don't know that you can only go to the post office from the side of the stairs, then you won't find it in your life. They asked an employee of a coffee shop nearby - they don't know!)
There are almost never queues at the department. Employees do everything quickly. I sent registered mail. They suggested how to arrange it. All the necessary information is posted on the stands.
