Worst train ride

The night train from Vienna to Verona was the most uncomfortable of all train rides I ever had. Even worse is that we had to be on it for about 12 hours! It was so different from the German night train that I took last time. If I knew it was an Italien operated train, I would not have booked the train. We should've just taken a flight. When we board the train at about 19:30, it was extremely hot and stuffy. There was no AC. We complained it was too hot and the conductor just rolled down the windows for us and said it'll be cooler later when the train starts moving. We went to check on the other cars and they were nice and cool. We wanted to move to the other car but the conductor said we're not allowed to do so. We can only stay in the compartment that we have booked. Sigh! I guess we're really unlucky to have been assigned to this lousy car. It got a bit cooler (from the wind) when the train starts moving. Then the conductor came and asked us to shut the window and said that the AC is now functioning. Well, after we shut the window, the AC was still not cool. Anyway, we got to enjoy the amazing mountain view only for a while as it started to rain and the sun was already setting. Then, we went to bed early but couldn't get much sleep.
