No, it isn't. Because a place isn't a video. No matter how many tens or hundreds of thousands of people know about some B&B room, no matter how "viral" it goes, only one set of guests can actually stay in it on a given night.

I've stayed in places whereby I phoned the owner to make a reservation and that was that. It is actually a "thing".

There are sites that aggregate listings of places like that without serving as a go between. It's not like the operators of the B&B just put up a page and rely on nothing but search engine indexing.

Airbnb is good for nothing if they have to comply with some city bylaw, the result of which is that you can't use them.
