Western Poland Destination Ideas?

I have just a couple days after a cruise and flying out of Berlin so would like to visit a typical small town in Western Poland. I enjoy anything scenic or historic, and would be happy just relaxing, taking walks, and sampling the food. Grandma was born in Poland so I enjoyed Polish food growing up. I will be traveling by rail. Ideas??

Visit Kostrzyn nad Odra, it's an hour from Berlin on the train and is a nice example of history. There's a lot to see there, and you can easily spend a day there.

Torun

The Krakow of the North

That was my first thought as it's a lovely little town but unfortunately it's a 5 hour train trip from Berlin. I also thought of Wrocław as although it's a city the centre is quite compact, but that is still a 4 hour trip away.

I don't know if it's nice, but Zbąszynek is on the Berlin to Poznan train line (not sure how many trains stop there now)

Łagów is a historic village/town (ein Dorf mit kleinstädtischem Charakter) between two lakes with the Castle of the Order of St. John from the 14th century. The place has not been destroyed during the WW II; is situated in the middle of the Łagów Landscape Park.
