The Diamond Head Beach Hotel was a good location for us as we did not want to be in the middle of Waikiki. It is located a short walk from a very nice public beach that has a sandy bottom and not much surf, also it was not very crowded In December. It was also across the street from Kapiolani Park where they have public tennis courts and pickleball play 4 mornings a week. It is not very convenient for walking to restaurants. I think there was 1 or 2 expensive and 1 burger/sandwich outdoor restaurant within 1/2 mile.
The unit has a good view of the ocean from the small living area and bedroom and also from the other side of the unit where the dining table is located. Good flow through ventilation from sliding doors and windows and we never used the AC even though temps reached a high in the mid-80s. The unit is small but it worked fine for 2 of us.
The unit has the feel of deferred maintenance. Small things like a screen door that kept falling out of the track, a broken electric outlet in the kitchen, and some peeling paint. Could use some new floor coverings. The elevator was out of service for a day and the water had to be shut off for an hour due to a faulty shower fixture in one of the units that would not turn off. These are relatively minor flaws but I expected a better maintained unit and building for the price.
