I have stayed at many Air B&B's and this one was hands down the best I've stayed at so far.
The hosts gave wonderful information and communication was fantastic. When we arrived, everything was amazing. There are plenty of utensils, pots and pans, etc. Kitchen is well appointed. Restrooms have plenty of towels. There are extra blankets. There is a high chair.
I will say you may want to arrive at the house first before buying anything at the grocery store - they may already have things that you don't need to buy. The grocery store is only a couple of minutes from the house, so it isn't an issue to run down and buy something. I rode the bicycle there to get supplies one morning.
There is enough room for two cars. There is also a little cottage in the front with a King Size bed/bath so if you want privacy, take that room. All the beds were comfy. We did the option to push the two twins into a King and it was fine.
There are plenty of beach towels and chairs - a lot of those. Snorkel gear for five persons. Several bikes. There are many beaches close by, one within walking distance/bike distance.
There is access to a private beach club that is amazing!
Everything about this place was perfect and fantastic. This will be our go-to place when visiting the Big Island!
