Nancy's place is great. There's a view of the ocean from her 3rd floor balcony - but no beach next to the property - just rocks. There are lots of nearby beach options.
Huge TV and comfy couches. Nice appliances if you want to do your own cooking. And the balcony is a great place to read, eat or hop on your computer.
It's about a mile walk into "downtown" Kona and it's along a busy street without sidewalks. But there's a trolley (it said $2, but they didn't collect money when we rode...) that stops a couple properties down the road. And there's Lyft. And parking is super easy at Nancy's place. But I wouldn't drive into Kona after 1pm because parking down there would be hard.
