Terrible service. The bus stop in Berlin (which was the second bus stop in the route) had absolutely no shelter so we had no choice but to wait for the bus out in the open while it was raining heavily. When the bus to Leipzig finally stopped by it had no information regarding its destination, the bus driver came out, shouted something to the people nearby and since no one answered he just drove off. We were further away because by that time we had tried to find some shelter from the rain and couldn't hear what the bus driver said. We continued waiting and only about half an hour later we realized that had actually been our bus and we had missed it. We ended up having to buy a last minute ticket for the train which became much more expensive than buying it 24 hours earlier. Cheap tickets but horrible service, would have been better to save the 10€ towards a proper train ticket instead.
