I do use IB Alon, I resisted it for my first 18 months of hosting because I felt I was not competent to handle the issues I thought may come with it.
In the end Airbnb virtually forced me into using IB by giving peferential search placement to IB users, and because I did not have much of a track record back then my views were slipping as I fell down the list in search rankings.
I reluctantly took it on board in November 2017 and Alon, I have not looked back since! At least 85% of my bookings now come via IB and I have only ever had one issue that was directly related to the booking procedure where IB is concerned.
I find IB guests to be of better quality that request guests....they like what they see and just want to pay and stay. Booking requests invariably come with questions....'can we bring our dog just this once?'.......'We have a restored 56 Chev, can we use your lock up garage for our stay?'.....'Does your breakfast allow for a gluten intolerant guest?'
Alon, all reasonable questions but, those lead in questions are invariably the tip of the iceberg and more will follow as they attempt to tailor your listing to their requirements rather than what you offer.
Under no circumstance would I now dump Instant Book....it is easily my prefered way of accepting guests and since adopting it have had far less issues than I had before.
Just goes to show Alon, we are all different, and that's what makes this such a wonderful world.....All the best.
Cheers.....Rob
