How to get there?: You can take public transport
Public Transport: Take S7 direction Riedstadt-Goddelau and get off at Morfelden-Walldorf-Walldorf Bahnhof…. äh?...anyway, From there follow your phone for 1,4 kms.
There is an option going with the S8 to the Airport and taking Bus 751 to Mörfelden-Walldorf-Walldorf Werrastraße. Check it out on the RMV page You still have to walk 600 mts. from there
Car: hmmmmm……..
