In all the times I have stayed at PBH (a ton

), the rooms that had fridges other than the minibar fridges were in the Villa Suites and above. In any other room, you have to request them.
We were in a Portofino Suite last November, and the only fridge was the minibar fridge. There is not a separate fridge in the garden, bayview and deluxe rooms.
In the Villa Suite and above, there is a fridge in the pantry but not in any of the bedrooms. If you want a fridge other than the minibar, you have to make a request for one.
The fridges are free if you have a medical necessity, ie, medicine that needs to be kept cool.
Otherwise, I believe the fee is $10 or $15.00 per night.
