Airbnb and hotels both have their place. Airbnb is at it's best in spots like coastal California where a place with outdoor space, cute decor, and a kitchen is really nice AND you can always go to a Holiday Inn off the 101 if things go sideways.
Avoid in places you haven't been to before or when you'd be really screwed if it ended up being unsuitable.
AirBnB works in my opinion best for very remote, or not-tourist travelled places. Where you're going to the island of Sørøya, for example, and there's literally no hotel space or otherwise accommodations available. Unfortunately, big business management companies exist in Norway too... go figure.
