If you are looking for a clean, comfortable, welcoming base of operations for exploring Hawaii, put Vicki's apartment on your short list.
I think the measure of any accommodation is the attention you receive from the host. You can spend a fortune on a resort or hotel, but if you're needs are ignored, you're going to be frustrated. Vicki is an outstanding host. Though we never met in person, she was always quick to respond to messages. We arrived to find a nice note, a gift certificate to the Green Flash coffee shop next door (outstanding breakfasts and smoothies) to make up for some sidewalk work going on outside the apartment (we were gone the whole time they were working) AND a bottle of prosecco which we celebrated my wife's birthday with. That's attention.
The apartment is equipped with everything you might need including beach chairs, towels, and a kitchen so well organized, I hang my head in shame at ours. It's located about a mile from the heart of Kona. It's walkable though Alii drive is pretty busy with cars and runners. It's easy to get in and out of for road trips. A car is a must. The pool is great with beautiful sunsets. The apartment complex is a mix of working folks and vacation rentals. Everyone was very friendly and the complex was quite quiet at night. There's no view to speak of from the apartment but don't let that dissuade you. It was the perfect place to come home to after a busy day taking in this beautiful island.
Oh, one tip for jet-lagged guests: the apartment is in building (A) on the right as you are coming in to the complex, not the apartment in front of the designated parking space, (building H) which also had a lockbox on the door. I hope I didn't scare anyone trying to open it.
