Crazy calculation - I recently had a guest, who got charged more when he changed to a shorter stay.
Rates was set to - Day: $50 - Week $250 - Month $750.
Now my guest asks for 56 days, two Airbnb months of 28 days, 2 x 750 = $1,500.
Fine, he is happy with the rate, books and transfer payment to Airbnb.
Later he requests for two days earlier departure and to his big surprise the rate now is $1750 for two days shorter stay!
How can it be so? Airbnb's rate calculations is quite opaque, no help there, so he contacted Airbnb and was told, that monthly rate only is valid for whole months.
Which means, that our guest was charged 750 + 3 x 250 + 5 x 250 = $1750 for 54 days stay.
No problem the representive from Airbnb told our guest, just request for a special offer from the host, but a special offer cannot be made after the reservation is done!
So the only solution is to shorten the stay on the Airbnb calendar to 46 days, 750 + 2 x 250 + 4 x 50 = $1450 which match the price reduction the guest should have for two days less stay.
Confused? so am I, not to speak about the poor guest, who is at the boiling point after countless problems and solution suggesttions to Airbnb's goofy calculation methods.
