There is another take on this. I have a rural property with 7 different apartments/rooms/places to stay. I live on site too. I am a host, I am here to welcome the guests and ensure a comfortable stay. I am an "onsite host"
I also have another property in the same village, I'm still here to welcome the guests and ensure a comfortable stay.
I also have another property, one hour away. I'm still availalbe (or one of us is) to welcome the guests most of the time.
But I agree the large company, professional property managers who never see a guest, probably does not really belong in Airbnb, and cannot be called "hosts"
We stayed at one of these properties in LA for the Open. The management was not professional, (non existant) and neither was the cleaning, and the surly doorman certainly was not welcoming.
I listened at the Open, with interest to host who successfully "remote control" their Airbnb's around the world, and have been awarded "superhost" status. This seem to me to be a misnomer - no host = not super to me.
Maybe the property housekeeper is "super", maybe the property owner is a "super" communicator but a host surely has to be present to be a superhost.
Think about it!
