Frankfurt’s City Center is called Innenstadt. You can walk around in about four hours and take in the old town, the River Main, the financial district, shopping, and a market hall.
In the city you’ll find everything, from department stores to bars, cafes, restaurants, a quick bite to eat, banks (including ATMs), churches, museums and markets.
Hotels are geneally upmarket, and the more centrally located, the more expensive.
A quick point to understand for those who are new to Frankfurt: Germany is a decentralized country, and Frankfurt am Main is the financial capital of Germany, and host to the Frankfurt stock exchange. Like New York, London, and other financial hubs, there is a mix of international finance and local economic activity in Frankfurt. What financial business goes on in Frankfurt also reflects the role of Germany in the world. Business aside, Frankfurt’s City Centre is an aesthetically pleasing mix of the old and the new.
For the ‘Old World’, visit the Old Opera, Goethe House, the numerous Chruches, and Römer Square.
For the new world, apart from skyscrapers and banks, between Hauptwache and Konstablerwache is the Zeil, a high street where shoppers can be seen buzzing between the numerous department stores.
Another features of the City Centre is the stock exchange, which is not far from Fressgasse, a car-free street of culinary delights catering to the office workers at lunch time and after hours.
For those who feel their budget is a notch higher than on Zeil, luxury shopping can be found on Goethestraße.
If you’re visiting just for a day in Frankfurt, you can easily walk around Frankfurt in a few hours. If you’re staying a few days, you can pace yourself and instead of rushing around, stop at different places and enjoy yourself with a drink or a cheap meal, like from the Kleinemarkthall.
To begin exploring Frankfurt, start at Hauptwache - the Old Guard House on the main shopping street 'Zeil'.
