You can click on the price on the page to see the price breakdown. I think what you see on the map is their nightly price, but when you click on it for the full listing you see the extra charges. The extra charges are service fees from Airbnb, some may be cleaning fees the owners charge, and sometimes places also have occupancy taxes. So all of those combined bump up the price pretty significantly. And because cleaning fees are in there and those are specific to each owner, there's no way to tell how much extra it will be from the price you see on the map.
I've seen prices here only jump a few dollars when owners don't charge a cleaning fee, to $30 because the owners charged a $20 cleaning fee plus the other charges.
Hope this helps!
