@Sven60 yes, the architecture is very inconvenient for people with many very similar rooms.
But please remember: Airbnb was created for individual hosts to welcome guests into their personal homes. That's why the system is designed the way it is.
And there are a lot of hosts who would honestly rather not have hosts with big hotels or buildings on Airbnb at all.
Airbnb clearly wants to branch out, and if they want to do that, they will need to figure out how to make it easier for the large-scale business.
But this is probably not the right place to complain about how hard it is for hosts with dozens of rooms to list. You might not get a lot of sympathy from people who would rather see hotels and the like go somewhere else.
