VAT charged by Booking to the Host

I am an Italian host. I read in the extranet website that Booking is applying a 10% VAT. It is unclear to me on which amount Booking will apply the VAT. 

For example, if I rent my house at €1000 per a week + €1 per day per person for local tax and assuming that I have 8 guests, I should be paid the following:

€1000 rent

€48 local tax

- €175 approx Booking fee (about 17.5%)

- ??? VAT - is this charged on the €175 Booking fee?

Are the other items of the calculation correct? 

Many thanks 

Simone
