Oh no, here we go again....bed bugs yet again!
This is becoming more prevelant with each passing month. Guests are becoming aware that Airbnb will close a listing until a certficate from a recognised exterminator is supplied, and these 'guests' (for want of a better word) are holding hosts to ransom because they know the host will do anything not be shut down.
Immediately flag this persons profile, tell Airbnb the guest is using extortion, and make a police report citing extortion as the basis for your complaint.
Ylva, you must never, but never try to negotiate with extortionists, blackmailers....whatever you want to call them. Every time you do it just gives them more power. Put as much heat on them as possible and if I were you I would open a complaint with the resolution centre to demand the return of money they have already had paid back to them by using false pretences.
What they will do is close that Airbnb account and open another one so, that is why you must involve the police in this, giving police access to their contact phone number so police can track their activity and at least make these individuals aware they are on dangerous ground.
So sorry you have been stung here, but you are simply one of a growing number of similar hosts. Time to hop to it and fire a canon or two of your own in their direction.
