I chose an apartment in Tangerang, Indonesia for a one-night stay. I chose the Instant Book option and without confirmation from the host, the reservation was instantly approved (and my credit card was instantly charged). I reserved the room a day before check in (April 25, 2017). Up until 11:00 AM in the day of the check in (April 26, 2017), the host never responded to any of my messages. As in any Airbnb booking, I need to have information on the exact location of the property (address and room number of the apartment) and also on how to obtain the key from the host. Up until noon, there was no response. And as I could not wait any longer, I then canceled the reservation. As the cancellation was made on the same day as the booking, my credit card was had already been fully charged by Airbnb and the host. I tried to explain this to Airbnb, but it turned out it was really difficult to contact and/or to find how to file a complaint. I think Airbnb has a great policy not taking complaints. Until today (my reservation was for April 26, 2017, while today is May 2, 2017), the host never responded to my messages and complaints. There were no responses from Airbnb. I used to use Airbnb to find cheaper accommodations. It however turned out that it cost me much more than that. Airbnb is a nightmare. I will never use it again.
