We've stayed in dozens of Airbnbs and this is the first one where we encountered so many problems!
The listing displays a den with a queen futon. The den is not private in the least. It's an open room with no door and if you need to use the bathroom, you need to go downstairs or go through one of the bedrooms to use their bathroom.
We had someone staying in the den and when we were trying to move the futon sideways to configure the room, liquid starting coming out of the bottom. The liquid immediately smelled like urine and stunk up the entire first floor. The property manager sent someone over quickly to clean it up and moved the futon to the garage (leaving dirt and debris everywhere on the stairs). As a result, that person had to sleep on a blow up air mattress that deflated every morning. Not what we were expecting to say the least.
The unit has an attached garage that fits two cars. However, the next day, the garage door opener broke (the spring had split away). We again called the property manager who said the door wouldn't be fixed until after we left the property. As a result, we had to park both cars walking distance from the unit.
The property managers were communicative and nice, but I would not recommend this listing. There are far better units on Kauai that would allow you to enjoy your vacation and not have to call the property managers multiple times!
