Perfect location for staying in Oahu. You'll definitely need a car and you absolutely do not need to park it with the hotel for $38 a night, we did street parking all 5 nights and didn't get ticketed. It's a quick walk to Waikiki and an hour drive from the North Shore. We would highly recommend. Only downside was that the bed was slightly uncomfortable and the mattress was difficult to sleep on.
Also, there's a bidet so that alone should convince you to book.
