Worst train experience ever!!! We traveled from Prague to Krakow (at least we were supposed to). No one asked us for tickets until we asked ourselves!!! The heating in the compartment didn't work. We asked the conductor if it would work. She said that no!!! There was -2 outside, and it felt -2 inside too. We slept in our clothes and wrapped in everything we had. It was very cold!!! Finally, we woke up in Rzeszów (2 hours out of Krakow). No one woke us up in Krakow! We asked the conductor how it could happen, and she just giggled. Just avoid this company as a plague!
