My mom and I spent five nights at Doug and Vicki's condo, which lived up to the hype from prior reviews.
It's beautifully furnished (I love the art) and fully equipped (tip: look into the little closet adjacent to the kitchen for spices and such). The A/C worked well when all doors and windows must be totally closed.
The lanai and primary bedroom offer great views of the ocean and Haleakala on Maui. However, due to the large amount of lava and sacred sites, you can't actually get close to the water.
If you go around the ocean club next door (great pool!), you can reach a trail. If you go south, you'll reach the Ocean Tower at the Hilton Waikoloa in about 15 minutes. The trail north is very dicey and not for the faint of heart. Since there is no beach nearby, we drove to A-Bay, Hapuna, and Mauna Kea.
Doug and Vicki were extremely responsive, sometimes responding to our questions in minutes.
The only issues that we had were the *very* firm beds, which are high off the ground, which was an issue for my mom. The bed pillows are pretty flat and need replacing.
We'll definitely consider Doug and Vicki's condo the next time we're on the Big Island. A few friends saw my photos and were interested, as well.
