I stayed at the Ocean View Suite for a week while attending a conference a couple blocks down at the Marriott hotel. The location was ideal and it was definitely a highlight to be able to take in the view across Diamond Head out to the coast each morning and evening.
As mentioned by other reviewers, the studio is compact, but it has all the necessary amenities and for one person this was totally fine. The air-conditioning unit was quite noisy, though I generally only used this for a few minutes to cool the room when getting in at the end of the day and then used the fan overnight. If you prefer a cooler room, this might bother you more! I’d recommend the Ocean View Suite if you need a comfortable and convenient base for exploring Honolulu and further afield.
