Hi there, not many replies i guess, as most here do not travel to that area of the island. First off, i would not consider renting a car, is can often be more trouble than it is worth . Bad roads, accidents, parking.... I think taxi would be your best bet to get around. Being that Ja, like everywhere has been closed for a while, the taxis will be very eager to get fares again. Feel out a few different drivers ahead of time, and get a price.. or wait until you get at the airport. There will be plenty options there. Since you are staying at an airbnb, they might even have a suggestion for you. Good luck, have a great , safe trip .
