I have a reservation with Avis next week, picking up Monday morning (07:30) at the train station in Frankfurt (am Main), Germany
However I am seeing conflicting information online about the opening hours of the location.
Called Avis locally (in Norway) today, and they confirmed the 07:30 opening hour but I am not convinced. Also tried calling the location in question but they are not answering the phone.

Anyone here with local knowledge, or with suggestions for how to determine this conclusively?

Need the early start to arrive in time for a wine tasting in Bernkastel...
The airport location opens at 06:00 but is also charging a lot more.
