For a curious traveler, Wiesbaden offers something that most German cities do not: a beautiful old town. In contrast to its neighboring cities of Mainz and Frankfurt, Wiesbaden offers an entire city of specacular vistas and 19th century atmosphere.

Basel is a charming and almost provincial counterpoint to the other great cities of the Rhine. Come visit for a beautiful but relaxed atmosphere and good food.
Frankfurt is not an especially pretty city. If you find yourself trapped here, asking, "What can I do?" the best answer is to go somewhere else. I aim to give you a list of places to visit within roughly 60-90 minutes by regional train from Frankfurt Central Station. The destination needed to have a direct or otherwise easy train connection to qualify. Likewise, it also requires an old town with enough things to do to fill at least half of a day.
Florence is a highly interactive city with many things to do and see. Below is an outline of when things are open and where they are located. I won't attempt to list every possible activity, but instead just highlight the main sights and some of the more complicated ones to visit.
Yes, Siena is what I would describe as "Peak Europe." It doesn't get better than this. You can think of Siena as a smaller and more subdued version of Florence. Florence overflows with tourists, who crowd vast avenues lined with marble-clad palaces. In contrast, Siena awaits a smaller crowd meandering through alleyways of sun-baked brick.
