Frankfurt

The best time to visit Frankfurt is during the spring (April-May) or fall (September-October) months. The weather is pleasant, and you can enjoy outdoor activities without the extreme heat of summer or the cold of winter.

Some of the top attractions in Frankfurt include Römerberg (the old town square), the Römer (city hall), the Frankfurt Cathedral, the Museumsufer (museum embankment), and the Main Tower for panoramic city views.

Yes, be aware that punctuality is highly valued in German culture. Also, it's customary to greet people with a handshake. When dining, it's polite to try a bit of everything on the table. Tipping is appreciated but not mandatory, usually around 10% for good service.

Frankfurt has an excellent public transportation system, including the U-Bahn (subway), S-Bahn (commuter train), trams, and buses. Walking is also a great way to explore the city center. Taxis and ride-sharing services are available as well.

You should definitely try 'Handkäse mit Musik' (sour milk cheese with onions and vinegar), 'Apfelwein' (apple wine), and 'Frankfurter Würstchen' (sausages). Visit the Kleinmarkthalle for a variety of food stalls and try traditional German cuisine in a 'Ebbelwoi' pub.
