Stayed for a month with two other guests. We did not have any issues for the most part. Jane & Johnnys family live above. Noise wise, we did not notice them only in the morning where you can hear cars starting and during dinner time.
There is ample parking on the street, which is nice to have near the area.
The only mishap was over the garbage disposal. Apparently it was left on even tho we used it as normal. What might have happened is the switch got bumped by an appliance. Its a quieter disposal. My other guests said it wasnt the most powerful one from the get go. Jane called the morning after and was quick to accuse and threaten to bill (only negative experience).
I would recommend Janes & Johnnys place for week long visits where you are quiet. I did have friends over for a Friday night and Jane said she could hear us play normal noise level movies and talking.
Its a value spot for sleeping, showering, and cooking. Then spend the rest of the time experiencing Oahu.
