Great beachfront location with balcony that you can see (a little bit of) the ocean from. We stayed for a week and exiting the building directly onto the beach never got old. The bed was comfortable and we didn't have any issues with outside noise at night. Having a mini kitchen was a huge plus - avoid the absurd brunch lines and just cook breakfast in the morning. Washer/dryer was great as well. There were also some beach chairs and towels. It really felt like a little home away from home.
Communication was super easy and we had no problems at all checking in and having our questions answered.
A few nitpicks - the floor is a little hard to keep clean. Definitely recommend following the house rule of not wearing shoes inside unless you want sand everywhere. It will still inevitably get in, and we wound up just getting used to it and wiping our feet before getting into bed. Also, the parking spot was quite a tight fit, you'll probably want to stick to a compact car or be good at backing into spots. The $25/night price was reasonable though (parking is unfortunately rather expensive in Waikiki).
