Very good drivers and they help you a little bit with English if you speak only English. The trip went well with no delays.
The only 2 problems that existed are:
1 - in your bus ticket it's written operator "Elite Express" but at the bus station the bus is not identified. You will have to ask help to Polish people to identify which bus it is because there are many buses at the same time.
2 - inside the bus there is NO toilet available. Sometimes the bus has to drive 3 hours and if you need to go to a toilet the bus will NOT stop until it reaches a fuel station with toilets to put diesel.
Everything was great, except that the toilet was listed as one of the available items, and turned out, it didn’t work. But we made stops on the way, so we could go to toilets outside.
