We are also VRBO owners, so in our humble opinion- this place should not be marketed as luxury.
Prepare to be surprised as one receives a check-in email (~1 hr before the actual arrival) that the entire property does not have drinkable water (the supposedly bottle water has never materialized); you need to use electricity responsibly and will be charged for excessive usage. That was a joke, I would much appreciate a heads up that island has power outage instead.
There is no onsite garbage collection, and you will need to walk outside the property. It's not a big deal, but it's not “luxurious or charming” by any means. (One will get the note that if trash is left upon one, it will incur a $500 fee.) There is About a 4-plus-hour outage daily, two days straight, while it is island-wide. Anything to mitigate would be nice—no battery-operated fans, flashlights, etc.
The walk to the beach is about 30 min - not a big deal for adults, but I would not walk with little kids, in some cases no side walks.
The property is a bit of a mismatch- leaving room and deck really nicely furnished. Bathrooms need a bit of TLC.
