Hello @Ericeira-SoulSurfers-Gue0,
On the website, you can go to your calendar and click on an available date. A window will appear on the right. It will have "Selected dates", "Availability" and "Nightly price" sections and, below that, a link "What do guests pay?". Click on that link to see a breakdown of what a guest will be charged.
To select more than one contiguous date click to enter start and end dates in the "Selected dates" section or drag the little "|||" on the date on the calendar.
The feature works only for available dates. It can't be used to see the price a guest paid for an already confirmed booking.
Steve.
