@Petra604 A lot of advice in here is slightly wrong.
Airbnb service fees do apply to all cleaning fees etc.
Also percentages are tricky little beggars
With the Guest paying the service fee if your nightly rate (including all cleaning fees) is 100 then you will get 100-((3% of 100)+VAT) and the guest will pay 100+(14.2% of 100 +VAT)
With the host only fee if you charge 115 then you will get 115-((15% of 115) + VAT) and the guest will pay 115.
Depending on your VAT rate if you have one the sums are actually quite similar.
