We had an outstanding stay here in Waimea (aka Kamuela). The photos don't do the place justice -- it's really much bigger and brighter than it seems in the photos! And it is situated at the top of a beautiful hill with gorgeous vegetation and dramatic views of the volcano. Really pretty.
A few things to note: wifi is excellent but we got no cell service, so be aware! Roosters at the end of the drive will wake you in the morning and a neighbor's barking dog may keep you awake at night. No heat or a/c in the house but plenty of cross-breezes and space heaters. We were there between Xmas and New Year's and the mornings were chilly but we were never cold.
Bedding could be updated as the pillows are flat and the sheets don't quite fit the bed but I'm being picky. The house is very spacious and new and quite spotless! But it's clear that there are a few builder-grade items that are ready to be replaced, such as the shower head in the master bath. Not a major thing. Still worked fine. Would have appreciated a few amenities like coffee or tea upon arrival, but we appreciated more that the place was bug-free and incredibly clean. It was easy enough to run down to Foodland for supplies when we arrived.
We were surprised to find snorkel gear and beach supplies in the garage closet, too, which was an added bonus. Plenty of beach towels to use and a clothesline on the lanai that came in handy for airing out wet swimsuits. We also took full advantage of the washer/dryer. It meant we could travel light, which was excellent. So much better than a hotel.
The town of Waimea (known as Kamuela on Google maps) is charming. We splurged on a dinner at Merriman's and were not disappointed. Foodland was great and had everything we needed. We also made a few stops at L&L for spam musubi!
If you're looking to explore the big island fully, this is a great central location about equidistant between Kona and Hilo. But be prepared: it's up at a higher elevation and that may be a deterrent for a few travelers. But it's off the main highway and as long as you're happy to drive 40 minutes each way to either the west side or east side of the island, this is a terrific home base for exploring.
