We had a great time at Nanjoo's place! The location was absolutely superb, one block from the beach and a short walk to the main thoroughfare of Waikiki.
The studio apartment itself was adorable and very clean. It was fully stocked with towels, linens, soaps, pots/pans, coffee machine. Nanjoo even left beach towels and sandals for us to use. The complex that the studio is in was pretty quiet, only minor noise from the complex across the way one night that we where there.
Nanjoo is very responsive and helpful. She even allowed us to check in and out early because that worked better with our flights.
There is a small parking lot on the ground floor. We never had a problem finding a parking spot, especially during the week. But we also went in late October, so it may get more crowded in the high travel months over the summer.
Overall, would definitely recommend this airbnb and would stay again!
