Great location, easy walking distance to the main spots in Waikiki and several buses nearby which can take you to downtown Honalulu, Pearl Harbour and the airport.
Samuel is very friendly and helpful, even offering me some of their Thanksgiving dinner! He also let me check in a little early and check out a little late, which was appreciated.
In terms of the space, it's a small room with a tiny but private bathroom which is clean and you have your own fridge in the room. As other people have said, it can be quite noisy, but then you are in the middle of Waikiki. It's quite basic, for example, no soap, shampoo etc but access to a kitchen with good equipment and plenty of oils/ spices.
Good option for the price.
