If you are looking for a comfortable stay that is out of the hustle & bustle of downtown Kona make sure you give Diane's place a look.
Located between Kona and your travels to South Point, Diane's rental is conveniently located. It's about 1/4 mile off of Hwy 11 with an outstanding view off of the lanai that has a view all the way to the ocean.
It's quiet & private with everything that you should need for your stay. Wifi, washer/dryer, usual kitchen amenities. We had no issues at all. There was even some wildlife. Mongoose, geckos (everyone's favorite) even a almost daily visit by a small flock of wild turkeys. I wouldn't worry about the coqui's. You could definitely hear them, but by the middle of the night there were usually only 1 or 2.
I would definitely recommend to anyone visiting the islands and is looking for a great comfy place to stay.
