1) The owners descriptions are misleading to the point of being fraudulent. A "Home" is whatever they choose to define. I wanted an entire home, as advertised along with pics and a full description of all the rooms. Turned out the "Home" was a single bedroom and bath adjoined to another "Home".
2) Dealing with Airbnb is the absolute pits. Nothing get's done, no responses, just nothing.
3) Home owners don't let you off the hook. There's no way I could find to cancel a Request. Its up to the owner of the property. If they do nothing, you're stuck as you can't make another Request for the same time period. I spent 3 days waiting for the owner to Decline. After that I tracked them down and, still, nothing has been done.
Given the amount of funds involved in any single transaction, Airbnb has a very long way to go before it could be considered a useful service. As it stands it appears the property owners are annoyed at the fees charged and the users with the service provided.
