Villa and location were pretty much as advertised. It was a cool, clean space and the location was tough to beat. There are 1000+ reviews for this resort at booking.com, so would encourage you to read those if you'd like more info.
We had the misfortune of staying in Byron during a cyclone that was a ways off the coast that brought some high winds. I believe it may have caused some power issues as our AC was not working at the time of check in and the gate for the car park did not work.
Maintenance issues happen, but the host was unresponsive to text/Airbnb messages for over 36 hours and we went without AC for almost 48. At this price point, the poor communication is pretty hard to understand, even if the cyclone is a valid excuse for the issues themselves.
The host eventually resolved the situation after I messaged Airbnb support and was very friendly when we ran into him when he arrived to fix the gate. His staff is very friendly as well so I assume that issues we experienced were more related to accessibility than anything else.
If you are an international traveler, I'd advise keeping this in mind as I never received a single communication through Airbnb from booking to check out. He seems to prefer text/phone, which isn't always ideal when abroad.
