Airbnb taxes to Puerto Rico

I just received notice from Airbnb that on August 1st they will start collecting occupancy tax. This tax will be charged to the customer and not to the host

Did Airbnb explain what "occupancy tax" is? I've never heard of it.

Airbnb also called it a room tax. They did not say what percentage it is but I will see it when I have a guest after Aug. 1 2017
