@Eduardo1274 It depends on whether you are in California and exactly what the wording of the order is. Once you have googled this and determined the legal position you just need to consider the common sense position as to what the risk of covid is to yourself and others.
I would agree with Mike and Jane. Consider the location that you are visiting. In my case, I host a cottage. it is a stand alone cottage on 16 acres. I have no interaction with my guests but by messages through the Airbnb site.
It is a little strange for me because how I choose to host but the host and guests must consider all risks and limit the exposure to everyone. Be safe and cheers!
