Airbnb government facility for tourists?

Is it possible to book an Airbnb in advance with tourist visa to do the quarantine? I heard some Airbnbs are considered government facilities as well, but I'm not sure if these are only available for owners of long-term visa.

And in affirmative case, would be possible for my gf (Korean living there) to stay with me and do quarantine together? I guess maybe in this case price would be double?

Thank you and sorry in advance if I made some English mistakes.
