Location: Very walkable to Walmart and adjacent to Chinatown. Walking might feel a bit sketchy like a lot of downtowns, especially if you're used to the touristy walk in Waikiki. Location is close to the highway to get around the island. Parking is great to have, and is on the 9th floor as others have said. While you do have to drive up to the 9th floor, it's easy to take the [internal, not external] elevator to the 12th floor to get to the condo.
Space: Very clean space, large bedroom. Great windows for great natural lighting in the bedroom. Bed and pull-out sofa were great.The kitchen peninsula, full fridge, and hot plate were great to make breakfast. I wish there were windows in the living room and kitchen, but it was fine. Bathroom was good and shower height water pressure was surprisingly good. There's no lanai though, so if you're used to using a lanai to dry off towels and swim clothes, you'll have to rely on the ceiling fans (there are two) to handle daily air drying when coming back from the beach.
Check-In: Ellie's instructions were perfect. There are a few sets of elevators in the building, but her instructions - follow her instructions step-by-step and it's easy.
Communication: Ellie was extremely responsive to messages. I really appreciated that.
