Hi,
Unfortunately I am currently in a situation where I left a belt behind at an AirBnb in Thailand. The host is slow to respond by email, and finally after days of waiting the host offers to ship it for 3x what the actual shipping cost is. I know this because I verified with the same shipping company.
When I raise this issue with AirBnb staff I get a generic response "I know this is difficult for you". What does that mean? Is AirBnb breaking up with me. Lesson learned is to be very careful about leaving items behind at AirBnbs, and whenever possible choose a more loyal hosting provider than AirBnb. I'm really displeased with AirBnb support in this manner.
The host wins either way in my situation. AirBnb's policy on this matter is not clear to me. The host either gets to keep my $600 CAD belt, or gets to make an extra $100 CAD by shipping it to me (on top of the shipping cost). Not fair, and definitely not cool.
