I would definitely recommend this place if you're on a budget. It's quite a bit away from the beach so keep that in mind if you're planning on spending a lot of time there. However, it's super convenient to both Ala Moana and the shopping district in Waikiki, which is more up my alley, so it was perfect for me.
The room itself is pretty small with a small kitchenette and bathroom. Probably not the greatest option if you're looking for something more homey, but just enough amenities if you're planning on being busy during the day and just need somewhere to sleep.
The kitchenette is stocked with some appliances, including a hot plate and some pots and pans if you do want to cook for yourself. There's also a quick and easy restaurant downstairs and a great coffee shop with malasadas, plus plenty of restaurants nearby. I would note that at least when I was there, there wasn't any dish soap, sponges, or a drying rack for dishes, so the few dishes I did use were somewhat inconvenient to wash.
Like other reviews mention, you share a wall with another unit and the walls are quite thin. This wasn't a problem with me as the neighbors were pretty quiet for my stay, but that's wholly dependent on who's staying in that room.
Check-in and check-out is super easy since you just pick up your keycards in the lockbox and then return them when you leave. The room is in an actual hotel building so there is hotel security as well, but I had no safety issues at all. There's also a pool (in case the beach is too far for you 😉) and coin laundry services. Pretty nice view from the 28th floor as well.
