We recently stayed at an Hikaru's unit in Waikiki and had a good experience. Communication was excellent and the 24/7 check-in/out process was seamless. The highlight of the stay was the stunning urban views from the unit, which was centrally-located with easy access to the commercial area and beaches.
That said, the building and unit were fairly dated. And there was limited storage space, as the dresser and closet were used for host storage, which made it difficult to unpack. Although we expected some street noise, we were not prepared for drag racing that made it challenging to sleep at times. The bathroom and shower were quite small, but not surprisingly so. Additionally, there were cooking smells from neighboring units that were noticeable.
Despite some challenges, our overall stay was fine and we would recommend it to others. This condo is a good choice if you're looking for a centralized, budget-friendly option. Just be prepared for some compromises.
