Considering the Hotel Adler in Frankfurt am Main?
A VT member wrote the following comment about visiting Frankfurt am Main:
Modern City by Leipzig
Frankfurt/Main is a very modern city. Except from the Altstadt (old centre) and some districts (like Sachsenhausen) almost all building were erected within the last decades. If you want to see old architecture you should visit towns in Frankfurt's vicinity, like Speyer, Worms or Heidelberg.
