The location can not be any better. We were able to walk to the beach, restaurant, shopping or took buses almost anywhere we'd like to go in Waikiki area. The studio has all the essentials we need. The hotel runs a coin laundry facility in the basement which we used quite a lot. You need to get your laundry detergent. There is a vending machine selling it in the laundry room. Very convenient. The host was very responsive and easy to reach. One night we lost power on main electrical circuit in the room which included fridge, microwave and network. Called/messaged Matt in the morning and he responded in an hour with instructions on how to put the breaker back on. We'd highly recommend the place to stay for the value and quality. The front desk usually do not provide much service as this unit is not managed by them. But they are surely friendly, informative and you can get changes from them if needed.
The room is quiet once you close the window. We never had to turn on the AC as the temperature was high 70's to low 80's. With night breeze it was quite comfortable. The neighbors were not loud neither.
One little downside that slightly bothered me, but not my husband was some kind of machinery downstairs most likely operated by the hotel. It sounded like a generator or central AC of some kind. The engine (or motor) kicked off every a couple of minutes. The sound was pretty loud and abruptly. When it was late night and the window was open, I was waken up every few minutes until finally fell into sleep probably because the machine stopped kicking off.
