Was attending a conference at the Hilton Hawaiian and arrived around 2am at the apartment block. Instructions for access were very clear and easy to follow and person at reception desk was cordial and very helpful.
Room was clean and had all amenities required for our 8 night stay. We had a great view of the park between us and the Hilton Hawaiian Village. Only issues we had was the curtain was white and thin which provided very little shading in the morning from the bright rays of the sun all day. TV was hard to view bcos of this. Patio sliding door is very thin which provided very little buffering to traffic noise from the Ala Moana Blvd down below. Bathroom is a bit small - typical of Japanese/Asian type apartment.
Also, access to the lifts requires a fob and you are only assigned 1 fob which means if you are without the fob you will need to ask the person at the reception desk to allow you up in the lift.
All in all, we had a comfortable and enjoyable stay
