I read a lot of 2/10 and 10/10 reviews, completely bimodal feedback: either terrible or excellent. I do not think they are completely fair. I would rate it 4.5/10. You need to dial down your expectations, these are really, *really* basic accommodations, not a “hotel” by any stretch. It is OK for a solo traveler who is not particularly picky.
I stayed for five nights for the Honolulu marathon. This YMCA is right next to the start line and just a short walk to the expo at the convention center. Incredibly convenient for my needs.
PROS: excellent location, 15’ walk to Waikiki beaches, relatively clean room, comfy bed, plenty of hot water in the shower, nice staff, low price, easy low-cost covered parking next door, several food trucks right in front of the building.
CONS: building condition is quite poor, it has not been painted in decades; no AC in the room; weak wifi, unusable at peak times; shared showers could be cleaner (definitely bring shower shoes); some bathroom sinks were broken; room facing busy road in front of building was VERY noisy; lots of signs with “rules” that would get you expelled (smoking, alcohol, washing clothes in the bathroom, having unauthorized company…)
Patrons appear to be a mixture of tourists and long-term residents.
Would I consider returning? Probably. But just if traveling alone.
