Arriving from Frankfurt Airport by public transport:

Hop on the tram S8 from the airport regional train station to Wiesbaden main station (final destination, in German: Wiesbaden Hauptbahnhof). Once you arrive, simply step outside the station and look for the line 37 bus stop, which is conveniently located right in front of the entrance. Take the bus to the Wiesbaden-Bierstadt, Venatorstrasse stop, and from there it's just a short 7-minute walk to Rostocker Straße 18-20. You can purchase tickets either directly on the RMV website or through their app.
