My most recent guest had one review that was not great. I have instant booking turned on and have never cancelled a request or booking since beginning to host in June of '17.
What could have turned out to be a 3 night making no money turned out to be one of open communication, sharing of a meal, laughter, understanding and great company. Getting to know our guest helped to reshape his idea of how wonderful airbnb can be, and is, rather than having to be "marked" as a "bad guest" from one review as a first time guest.
As a 5 star rated superhost who works very hard to ensure each and every guest is treated fairly from the moment they see my pictures, and decide to book, regardless if they are new to airbnb, have no reviews or very few, I give them the benefit of the doubt....always remembering that we all, as a host and as a guest, have good days and bad, that humans are kind, can have a change of heart and deserve second chances.
We spend so many hours bashing airbnb's rules or ratings and/or algorithms, the reviews guests are given to be "the only factor for letting them be a part of your home"...."I call BS" (keeping with the times, that comment was to honor the Parkland HS students)
For the Host that actually had "first dibs" to have my guest stay three nights and declined because they said, "we read your {one} review and we just can't have you here" I reply with what a shame because you missed out on being able to help this guest understand what airbnb is and can be.....Changed attidudes, Changed minds.
My guest came thinking my place was going to be the last time he'd ever stay with a host again to looking forward to his next stay at another fantastic, hard working, dedicated airbnb host family's home!
