Berlin Gesundbrunnen - Krakow Glowny, first class sleeper, a ticket seller offered me an discount ticket which offered a first class sleeper bed at the same price of a second class couchette.
Rome Termini - Florence Santa Maria Novella Eurostar Italia, second class. I missed a regional train, which does not cost a supplement charge. I have to purchase a Eurostar ticket. A stupid thing is that my seat did not exist in the coach! I and other passengers were astonished at the ticket. I had a vacant seat and waited for a train crew. However, he did not come.i
