In 2-3 days or on a long weekend you will get a good impression of the city.
The famous Römerberg or "Römer" is the town hall square of Frankfurt. Here you can sit in a café and let the complex of buildings take effect on you. A little further, but still in the city centre, is the Maintower, which with its height of 200 metres contributes to the characteristic cityscape. For a small fee, one can enjoy a view to Frankfurt am Main from above.
Sachsenhausen is the oldest district of Frankfurt am Main. Here you will find pretty alleys and historic half-timbered houses. At night there is a lot going on here. In Sachsenhausen there are a lot of bars, pubs and clubs. If you want to visit many sights, the old town is the best place to go. Here you will find, among other things, the market place, the Römer and the Kaiserdom.
One should visit Frankfurt am Main in the summer. At this time, the famous Palmengarten shines in all its glory. There is also after-work-shipping in Frankfurt in summer. On these ship tours, people dance and celebrate under the open sky. The night skyline can be admired from the water.
In the 25hours Hotel The Trip with its cool design there is a beautiful roof terrace including a view of the skyline. The Manhattan Hotel has everything a city hotel needs, especially of course a great location right in the city centre with great connections. In the 5-star hotel Steigenberger Frankfurter Hof you are not only in the cultural centre, but you can also relax in the 1000m² wellness area.
