The good: the ocean is right there in front of you. It is a crazy beautiful view. The sound of the waves is constant. We slept with the windows open every night. It is cooler in December, so no issues with not having an a/c. We actually might have used a heater one night if there was one in the unit. You will see whales and dolphins if you sit and watch the ocean long enough. We did everyday. There is a nice beach a short hike from the unit. The neighborhood is quiet and very safe. Fewer rooster noises here than in the other places we have stayed on Kauai, but maybe we just got lucky. Close proximity (less than 30 minutes) to Haena State Park and many more beautiful beaches and hikes.
The bad: the unit is extremely dated. A little $ and TLC would go a long way to making the interior a more comfortable space. The upstairs neighbors were loud both at night and extremely early in the morning. Sounded like they were constantly rearranging the furniture. Because the view is so ridiculously beautiful, occasionally people walk by the back of the unit past the windows and sliding glass doors, so if you don't want to be seen naked you need to exercise modesty at all times or close the drapes and lose the reason for renting this place.
