There is no acceptable cancellation of a guest reservation by or on the part of a host Stefano. If a hosting cannot take place you must contact CS and ask them to relocate the guest.
What will happen then Airbnb will contact the guest and give them three options.
If you have a problem that is going to impact on a guests stay (which falls outside the extenuating circumstances clause) you can contact CS and ask them to relocate/refund the guest. CS will then contact the guest, explain the situation and ask if they would consider a relocation.
The guest can either say...
A/. 'I would accept a relocation' to which the agent 'may' offer a monetary 10% relocation offset as the cancellation was a result of the hosts inability to proceed.
B/. 'I will accept an alteration of dates for your reservation'?
C/. 'I would like to cancel my reservation.'
CS would then return to you with the guests decision and the reservation would either proceed, be changed in some way, or would be cancelled.
Where the grey area comes in is, in some instances guests do not automatically get the Airbnb service fees refunded if they cancel and CS may advise them that if the host were to cancel the reservation there would be no penalty to them, the guest, and you would receive a 'request to cancel' email which makes you responsible for the cancellation.....and this is what happened to you last year....you received an email saying the guest would like to cancel and you said ok and hit cancel!
I would really be having a go at getting this last cancellation penalty removed Stefano...after all circumstances were beyond your control and you will find your reservation requests will come back if you do not have that black spot remaining in your reviews.
CS are living breathing humans with a heart and with feelings (unlike computer programs) and if you go about this in a passive way there is every chance you will be successful in having this last cancellation removed from your record.....All the best mate!
