Very nice and clean little apartment. As some other reviews mention, the pictures make it look a bit bigger than it actually is, but it was pretty much just as expected and big enough for 3 adults.
There was a showed gel, shampoo and plenty of towels in the bathroom, big fridge and freezer and microwave in the kitchen and a lot of storage space.
The bed wasn't the best as it was a bit soft but that's just personal preference I guess.
Probably the only downside were the tenants in the upstairs unit, they were always home and walking (stomping) back and forth around the apartment very early in the morning, we could hear every step and were very glad when they moved out.

The area is nice and quiet, about 10-15min walk to Waikiki Beach and Honolulu Zoo.
Safeway supermarket about 20min walk and highly recommended Rainbow Drive-in just around the corner.

My sister got there before us and did the check in, so I never really met Chifumi, only saw her once a few days later. Daniel, who lives in the other ground floor apartment is a great guy and great host, very friendly, gave us some tips for our trip around the island and even did a BBQ for all the guests one day. His little girl is super cute and adorable and always wanted to play with us and visit our apartment :)
His dogs are not that loud and didn't bother us at all, they're also quite friendly, especially the smaller one.
Overall, it was a very good experience. If I ever go to Hawaii again, I will definitely consider staying there again.
Mahalo Daniel and Chifumi for a great stay.
