Krakow

Krakow emerged pretty much unscatched from World War bombing and hence has an abundance of old architecture to lure many travellers. This also means that there are a lot more English speaking people here, as tourism is quite strong.

Leaving Krakow you have limited options. A stop in Zakopane in the mountains is apparently well worth your time. A train to Prague will take about 8 hours, so a sleeper train is a popular option. However, it is cheaper if you get a train near the Polish border, walk over and then catch a train in Czech.
