Hi,
there are several options, all depending on the type of aircraft and which flight rules you're following.
Reichelsheim would be an option:
Flugplatz Reichelsheim in der Wetterau
Airport data:
AIRPORT Flughafen Flugplatz Pilot
See the pilot reviews on this private website:
eddh.de - Landeinformationen
You could use google translator on eddh.de
For fuel prices etc.

Hope that helps, have a good trip : -)
