This station in west Frankfurt is right next to the Messe / Trade Fair grounds and has direct…read morepedestrian access to the halls. For me, this is the station that was closest to my hotel along Europa Allee - a short walk along a reasonably well lit roadway.
Not much for services here at the station. I did not locate a free wifi hot spot while I waited for my train. There do not appear to be any snack or vending shops here though there are a couple of vending machines on the platform. There is also an automated ticket machine. It is reasonably well lit and the platforms can be seen from the Emser Brücke, so I felt somewhat secure.
The station is served by S-Bahn lines S3, S4, S5 and S6. It is between Frankfurt West and Galluswarte stations.
Unless you're headed to the Messe, do not exit to the south.
