A good train station, there are many shops, cafes. We never stayed for a long time, but as such there is no large waiting room, we always sat in a cafe, drank delicious coffee with sweets. Everything is clear on the scoreboard, there are elevators and escalators to the platforms. There are many shopping centers near the station, there is not a large Kaufland nearby, in Lidl station
The Grand railway station, the central part of Germany. You can leave both on fast trains and on regional ones. Be prepared for a huge number of people. Food courts are open even on Sunday, which is not often found in Germany. There is everything, you can even go shopping.
