I am looking for a new property management platform and I recently spoke to a sales rep at LittleHotelier who said they are "working on the Airbnb integration", which makes me nervous as it seems they have been using that line for awhile. In my research, I did come across another booking Platform called LiveRez that does have Airbnb integration. Unfortunately, it's pricing model is based on bookings, instead of a flat rate. In addition, there is a high initial cost to create your website and then it is on their proprietary platform/servers, so you no longer own your own website, which I am not comfortable with.
I agree that AirBnb should release a list of approved channel managers.
