We love Waikiki Shore because of the proximity to the beach, shopping and restaurants. We have stayed here 3 times. Pros of the building: secure, super clean, roomy, convenient, front desk is helpful.
Cons: city noise can be a bit much starting at 5 am (sirens, busses, traffic) sometimes hard to get in and out of underground parking due to lots of pedestrian traffic. Front desk only open until 6:00 pm.
I would highly recommend Waikiki Shore.
