@Gary782 I looked at your listing, which looks quite nice.
I would advise you, though, to change the following wording in the Interaction with Guests section "Guests will have full use of the house and will not be disturbed by the hosts (unless they have questions or require assistance). Hosts available via WhatsApp, Viber, SMS and/or email."
First of all, giving guests the impression that seeing or speaking with the hosts is a "disturbance" is not something you should promote. In order not to have guests who think they can throw a wild party, sneak in extra guests, etc, it's much better for guests to be under the impression that you are just a stone's throw away, could drive by anytime, etc. Your listing is already for an Entire house- it's not necesssary to keep stressing that fact. "We live very close by, so can be readily available should you need assistance or have any questions" is a better message to put out.
And DO NOT communicate with guests in the ways you have stated. You want to communicate with guests via the Airbnb messaging system as much as possible, especially in a listing where you don't live on-site, so there is a record for Airbnb look at should there be any dispute between you and a guest. Phone calls and texts are okay for a few things, but really risky in a lot of ways. Your guests are complete strangers to you, not your buddies who you text and Whatsapp with. You want to maintain a record of what is discussed between you and the guests, so if things go sideways it's not a matter of I said, he said, no you didn't, yes I did.
Guest: "We can't figure out how to turn on the XX and can't find any YY."
Host: "Just push the widget and wait 5 seconds, then turn the knob to the left. The YY is in the second drawer down to the right of the sink."
Guest: "Thanks, very helpful. Got it."
Guest decides to cut their stay short, for reasons having nothing to do with your place or your hosting. Calls Airbnb to demand a refund for unused days, claims that the XX doesn't work and the host was unresponsive and refused to help out.
Would you really want that previous conversation to have happened by phone, or would you want to be able to say to Airbnb "Check my message stream with the guest. His claims are obviously bogus."
