Some positives: the host was very accommodating and responsive, and provided some nice amenities like sunscreen and bug spray. The location is excellent and super convenient for getting around Kona. The space is rather large, albeit somewhat utilitarian, and the kitchen was well-furnished.
However, this place was not exactly what we were expecting. The space was technically as advertised, but the photos in the listing make the space look a lot cozier than it actually is. There were 3 major issues I had with the space:
1. Airflow. There are 3 windows in the space, but two of them have holes in the screens, letting bugs in. The third window looks onto the backyard and, when open, picks up all the noise coming from outside and upstairs. Without the windows, the only option for airflow is the AC unit, which doesn't reach into the bedroom well.
2. Privacy. One thing we weren't aware of until we arrived was that the wall that separates the bathroom from the rest of the space doesn't run all the way up to the ceiling. There's about a 1.5 foot gap, which lets both light and sound from the bathroom into the rest of the space. If you're going to stay here, make sure you and your travel companion(s) are REALLY comfortable around each other!
3. NOISE. There is pretty much no insulation between the ceiling of the space and the floor of the upstairs unit, because we could hear EVERYTHING. Footsteps, doors opening and closing, stuff falling on the floor, toilets flushing, you name it. While a little upstairs noise isn't a big deal, because the space is so cavernous, all of the sound from upstairs echoed throughout the space. It was pretty difficult to watch TV or even just relax when the hosts were home because of the noise level.
This space has a lot of potential, and met our basic needs (sleeping, showering, eating). However, we likely wouldn't stay here again.
