We agree more than completely with what others have so beautifully written before us - the place is truly like the most lovely comfortable place you have ever lived in - photos cannot do it justice and its even more impressive that David built everything including the amazing bathroom tiles (house envy; David please come visit and tile our place too!)

We stayed two nights and wish we could've stayed longer.
The kitchen is fully functional - you can cook anything there.
Coffee and tea is well stocked and theres also an amazing fruit basket which we delightedly demolished (thanks!). We have two growing lime trees and will look forward to being able to try David's papaya/lime combo again in the future :)

They have two lovely dogs which, as people have mentioned, cause absolutely no problems for those who are not used to dogs. They keep them either inside or safely fenced.
Wifi works smoothly, the bathroom was clean and fully stocked even with beach towels, there's info on virtually every restaurant and of course the national parks/lava and Big Island sights.

Read David's instructions clearly - we were so used to using GPS to get to our places that we didn't notice (until we ended up on a maze of gravel roads) that we couldn't reach the house via GPS alone.
BIG TIP: either don't use GPS and follow David's instructions word for word, OR if you use GPS - type in "S Kopua" then you'll be able to enter their address once you're on that road.
If you end up on a gravel road, you're heading in the wrong direction!
The roads to David's place are fully paved.

We were on Maui before the big island and hadn't heard the amazing call of evening frogs until we got to Mountain View - absolutely stunning! We made recordings and sent them to almost everyone we knew. I'm not sure you would hear these if you were in central Hilo. It was lovely hearing Bonnie describing their garden forming from scratch, which obviously provides a home for the frogs and birds.

We highly recommend a stay here. It is more than amazing (and we have stayed in many air BNB's over the years). Very impressed.
Thank you David and Bonnie!
