Location, location and location! The most appealing part of this unit is its location within Waikiki. Its walking distance to the beach, the shops and all restaurants that exist within - no need to drive or find and pay for parking!
The unit is definitely dated, but completely clean and doesn't get the direct sunlight (and heat) from the windows. I did notice the limited number of available outlets for charging our phones at the end of the day - the ones I did find required a bit of muscle to plug in, others didn't seem to fit at all. That said, minor inconvenience for the great location.
The only other complaint were the elevators - understandable as there only seemed to be 4 elevators servicing the 30+ floors they had, but its 7th floor location meant that you could take the stairs if you had a car and parked on the "higher" floors of the garage -- it was faster to get to/from instead of waiting for the elevator.
