I think we’re agreed that quarantine in a home (i.e., apartment/townhouse/detached house) is okay. Provided every adult undergoing quarantine has their own room and bathroom to prevent back-and-forth transmission. And that home can be your own residence, a long-term rental, or a short-term rental, like an Airbnb. I know an Airbnb is okay because I told the screening officials at the airport I would be staying in one. But, the Airbnb host needs to know and approve of you to use their residence for quarantine purposes.
One question in this thread is if hotels not on the quarantine hotel list can take in those undergoing quarantine. I don’t know the answer. But, if a hotel is willing to take those undergoing quarantine… why not just add themsevles to the list? And if the government workers know you’re going to a hotel to do quarantine and the hotel isn’t on the list, why wouldn’t they make the hotel put itself on the list?
