I have been part of the Air BNB community for a long time and had many stays good and slightly bad. When it comes down to it, the integrity of the host counts for most of the experience no matter what. Bradley and Melissa had a chance to do what was right regarding an unforeseen cancellation due to illness. There are ‘policies’ but there is also fairness. They ran and hid behind AIR BNB, changed their story and in the end took my $ when it was unnecessary while they could have at least compromised. There are hosts that are concerned with their guests stay and there are those that strictly want to take your $$$ no matter what. Sadly it is obvious these hosts just want your $$$. If I were you I would find a property with a host that is fair because if problems arise with your stay I can say with confidence this couple will NOT care.
