Poland was one of the few European countries that neither of us had ever visited, so when we saw a tour advertised that would take us there by rail from London, we were very interested. The chance to revisit Berlin en-route sealed the deal, because it is a city we love. The itinerary took us to three Polish cities; Wroclaw, Kraków and Warsaw, from where we flew home.

The journey started here, at London's St Pancras Station.
