Overall would highly recommend this for a Waikiki stay! Located two blocks from some of the best stretch of calm beach (especially for children), convenient coffee shop / mini mart in building, walkable to restaurants, shops, and activities. Parking included which is a plus and easy to get away from Waikiki on the H1 etc. New floors, great lanai overlooking the pool and Diamond Head! Bed is comfy (if you like soft mattresses). Didn't try the sleeper sofa but I imagine as expected with those types of things. A/C definitely cools down the whole place as long as you keep it on but noisy.
The elevators at the Waikiki Banyan (not in hosts' control but it took us 20 mins+ some mornings and afternoons around check out / check in to get out of the building!) Bathroom needs some work but overall the place was clean, quiet and as you see in pics.
