About the location (from Wiki):
The Römer (German surname, “Roman”) is a medieval building in Frankfurt am Main, Germany, one of the city’s most important landmarks. It has been the city hall or Rathaus for 600 years. The Römer merchant family sold it together with a second building, the Goldener Schwan (Golden Swan), to the city council on March 11, 1405 and it was converted for use as the city hall. The Haus Römer is actually the middle building of a set of three located in the Römerberg (a plaza). The Römer is not a museum as it is actually used by the city for various purposes, for example as a Standesamt or civil registration office; the wedding rooms are located in the first and second floor of the Haus Löwenstein. The entire three-storey building complex occupies about 10,000 square metres and consists of nine houses, encircling six courtyards. The front, with today’s main entrance, faces the Römerberg plaza. Other streets around the Römer are the Limpurgergasse to the south and the Buchgasse and the Berliner Straße to the north. The Braubachstraße divides the south and north wings.
