Fly, swim or run to Frankfurt or Darmstadt!
From Frankfurt Airport:
Take the Darmstadt Airliner, from Bus stop #14 at Terminal 1 to Luisenplatz Darmstadt.
At Luisenplatz take the L Bus in the direction TU Lichtwiese.
Get off at stop "Beckstrasse".
Kiddy-corner from you is a bakery called B�ckerei M�ller. I am in the top floor of this building.
From Darmstadt train station (Hauptbahnhof):
Take the D Bus towards Darmstadt Ostbahnhof, or H Bus towards Kranichstein Parkstra�e, to Luisenplatz.
Take L Bus same as described above under Airport.
Note, the city busses cost 1.25 Euro, regardless of transfers.
The Darmstadt Airliner costs 6.60 Euro (I think).
