We've enjoyed staying in this unit for 3 weeks in July with our two kids. Every evening we've unfolded the sofa in the living room for them to sleep. We had to leave the sealing fan on every night, because it was hot inside, even if the window is open, and during the day when we were at home. In the bedroom we've used the air conditioner and the fan. We've turned off the AC just before going to sleep.
There are plenty of towels in the bathroom and closet. Having washer and dryer in the unit helps a lot. You will find everything you need in the kitchen, including some spices. Dish washer is very efficient and clean.
In the closet on the lanai there is plenty of beach equipment, including chairs, boogie boards, cooler, and sand toys.
Location is great! Only 3 minutes' walk to the Kamaole III beach, and if the waves are big, then continue to the Kamaole II beach (another 5 minutes), and in the evening again everybody is gathering for a sunset at the huge grass area at the Kamaole III (only 2 minutes). Since you can see one of the swimming pools from the balcony, check how many people are inside before you go for a swim because the pool is small.
The grill near the pool is well maintained and cleaned every day, so definitely take advantage and cook a stake for dinner.
There are also some restaurants and a great ice cream place in walking distance.
