There are few options in Waikiki with a full kitchen (nice for eating in take-out, snacks, etc.), fewer still with a closed, separate bedroom. This has both, and is as close to the beach as you can wish without being right in front. Add to that a nice clean and renovated feel, the courtyard with shower to rinse the sand off, the available beach toys and accessories you can borrow, and just a nice feel in that well-kept seventies building. But above all, the location is what makes this such a gem; the lack of private parking is offset by being in walking distance to anything you may want to do. If ever you want to do an excursion (e.g. Pearl Harbour), you can take a city bus. For everything else, you can take a biki, hail a uber, or simply just walk. Not having to drive adds to the relaxation.
This was our first time in Hawaii and we will be back, and will be wanting to stay there again.
