We (4 of us, including 2 kids) stayed at this old beach house for about a week. We were going to stay longer but a bug infestation caused us to leave earlier than planned. More details:
This house is on the far end of Malaekahana Beach on the east side of the North Shore. You can access the beach through the yard, which is nice and is the main draw of this house. The yard is large and private. The section of beach right in front of the house had a lot of rocks and sticks, but if you walk down about 15 minutes along the beach, the sand is great with fun waves that the kids enjoyed.
The house itself is old and smaller than it looks in the pictures. Overall, it has not been kept very well up to date, with the exception of things like the flooring. Also note that there is no A/C -- while at night you might get by with the cooler breezes, during the day it gets pretty hot inside. It is located in the "country" -- there is no trash service, there are stray cats and chickens, and you have to lock up a chain link fence. Location-wise it's a close drive to some great food trucks. The property manager Jen was helpful and responsive throughout.
The house wasn't unclean as such, but the main issue that we had was with a bug infestation. A couple of nights in, we discovered a lot of bugs suddenly crawling and flying around the kitchen. I didn't know what they were -- after communicating with Jen she found that they were a type of flying ant (3-4 times as large as the ants we're used to, with wings). They eat wood, and had somehow gotten through the walls (we kept the doors closed throughout our stay to keep bugs out). I cleaned up the bugs that night, and Jen had a pest control person sent out a couple of days later to spray. This seemed to help for a day or so, but then they started coming back. Typically in the night, they would find new holes to crawl through and enter the house. I was spending time every evening to manage them, but it was becoming increasingly difficult.
Finally it reached a point where one evening we found 100's (literally hundreds) of them crawling through holes in the bedrooms walls -- both the primary and the bedroom where our kids were sleeping. They would then crawl on the walls, fly around and get into the bathrooms, onto bed sheets, lamp shades, etc. It took my wife and I hours to clean them up and try to keep them out at least for the night. But it became stressful, unmanageable, and unenjoyable. Jen assured me this had not happened before and was seasonal. That could be; I don't know. But I will say that the house, being quite old, not kept up well, and not protected against this sort of infestation, made it easy for the bugs to crawl through holes that the house is riddled with (some of which I imagined they have created over time).
We communicated that the situation had become unacceptable and unlivable to Jen, and she responded quickly and was as helpful as she could be. We requested that we cancel the rest of our stay, and to her and the owner's credit, they refunded the rest of our stay. We then stayed at a hotel for the remainder of the trip.
I want to present a balanced, transparent view of our experience. There were aspects we liked about staying here, mainly the location and privacy. If you know what you're getting into, and are expecting it for what it is, you could have a better experience with it. However, my view is that this house needs to be significantly updated (not in cosmetic ways but in basic ways) before being rented out again.
