I frequently (multiple times per year) rent AirBnBs for the full kitchen and many bedrooms for group meetings where we live, work, and cook meals together.
I've never seen an 8 bedroom 6+ bathroom suite with a full kitchen in a hotel. I've only looked in a half-dozen cities or so where I've wanted to hold these team events, but I've never seen one.
Often in AirBnB you can find a stand alone house. In a hotel generally you have a hallway with rooms, one of those rooms is yours, and all the other rooms belong to other people.
The stand alone house can have a yard or a distance to the next house.
Sometimes you can find AirBnb right near a place you need to be in the next morning whereas a hotel might need to be a long ways away and travel between the locations can be problematic.
airbnbs are cheaper if you don't mind sharing the bathroom with other guests/host and cook all your meals in host's kitchen. This has saved me a ton of money traveling over the years.
