You need to choose the time to go to the post office. In the morning, as usual, there are a lot of people everywhere. It is better to go closer to lunch, you will wait less for your turn.
A good post office. The staff is polite and pleasant, there are no long queues (1-2 people maximum). Quite a convenient location, there is a bus stop near the branch, you can get to the post office by minibus or bus
