We enjoyed our stay a lot. The unit is surrounded by gree garden and you hear nothing but nature. However supermarket, drug store and gas is all nearby.
The unit had all the essentials, along with hotel-like amenities like shower gel and earplugs.
It was really a great stay, easy to find and communication was great.
But you need a rental car - which you need on Big Island anyways, so make sure to rent it directly from the airport.
