I stayed here for a month and really enjoyed it. The view was great. The apartment had a modern feel to it. The unit cleverly conceals the fridge and laundry in the cupboards to make the best use of the sq footage of the unit.
The bed was comfortable. The building itself had a couple new exhaust fans installed on the roof which kick on and off all day/night, so I slept with the A/C on to drown out the noise. Waikiki is always noisy no matter where you stay, so you probably want to sleep with the A/C on anyway.
The A/C unit itself worked great, and kept the room as cool as you would want to keep it. If you open the windows you get an fantastic breeze coming through the unit. The exterior walls are all windows, which gives you a nice panorama of the mauka side.
Communication with the host was easy and fluid.
