Our host was great and very communicative throughout our stay. My only advice to travelers is to reserve a parking spot in advance because parking is very limited! We had forgotten to do so and only managed to get parking because Kurt and Irene offered us their spot at the last minute at the super reasonable rate of $20/day. We would not have been able to make this trip work without their generosity, so for that, we are eternally grateful to our hosts.
The Waikiki Grand Hotel (which the room is situated in) is an older building so it will definitely lack the amenities that you might get at a newer, pricier, more modern hotel. That said, our room was clean, had adequate air conditioning, and came with an amazing view of the beach. The 10th floor deck provides an even better, unobstructed view of the ocean but is closed relatively early in the evening (10pm) as there are also guests on the top floor. Hula, a bar on the 2nd floor, was a reliable spot for evening drinks that were quite good quality + affordable! (skip the food though. haha). I later found out that it was the oldest continuously running gay bar in Honolulu, which was a nice little piece of Hawaii history to learn. The place was also walking distance from a ton of restaurants both on the Waikiki strip and further into residential Honolulu. The only small downside was that the full-sized bed was a bit small for both my partner and I, but other than that, no complaints!
