Note, posted as an answer: Hermes does no longer transfer luggage from the airport or to the airport. They will only pick up or deliver to hotel or a private address.
I want to use Bahn Gepaeckservice to send my luggage from Frankfurt Main Airport to an Airbnb in Chemnitz. The Airbnb is a private apartment. I'm a tourist and do not live in Germany. The Bahn's web page mentions:
Selbstverständlich übernimmt die Gepäckaufbewahrung auch bei Ihrer Rückreise den Gepäckversand nach Hause.
Which means the Bahn (or the airport's luggage service) will send the luggage from the airport to the persons home ("nach Hause") — which I assume must be in Germany.
I already asked on bahn.de but the answer does not clearly state that tourists can use the service and they directed me to the airport's left-luggage-office (although it seems the Bahn is offering this service).
Can a tourist (non resident) use this service to send luggage to an Airbnb address?
I'm worried that the Bahn wants to see an ID document which shows a permanent address in Germany.
If I can use the service, where do I go to at the airport — the Bahn or the left-luggage-office?
Alternatively, can I send my heavy luggage from Frankfurt airport to Chemnitz some other way?
