Location could not be better. One block from Waikiki beach, so you are right there, but there is a building between so it is quieter than being right above the main street. Kawika is Alan's assistant, and was super helpful. He knows the local areas really well and made some good recommendations.
The penthouse was high enough for a good view but low enough that there was never much of an elevator wait. We had 4 adults and 2 children and never felt crowded.
The rooms are all actually larger than they appear in the photos. It came with beach towels and folding chairs that we could take to the beach. The outdoor lanai (patio) was very large. The free parking spot made it so much better than a hotel, all of which charge for parking. Having a full size kitchen with pots, silverware, plates, cups, etc was very convenient. Also, there are several very good food trucks within a few blocks.
