The worst airBnB experience ever - these are the facts and what happened to me. Hope this does not happen to any guests in future...
1. The host was out of Japan and the phone number listed was out of service
2. The host accused me of not using a specific communication app in Japan
3. The host didn't provide key box number due to security reason (although there was a clear description on the website "use keybox if host was not there")
4. Then, the host suddenly cancelled the reservation over the phone, leaving me near the house at night. I needed to find an another place to stay that night and the rest of days in Tokyo.
