Nobu's place is awesome! It is a very convenient location that is located just off the main strip in the Waikiki area with everything within 20 minutes walking distance. The extension cord available was underrated and the Coconut themed shower gels were an awesome touch.
We also rented a car and although it was a pretty busy week after the New Years, we NEVER paid for parking! As long as you are comfortable with a 10-15 minutes walk, should not be an issue! For the weekends, I would recommend parking on the other side of the Canal as there is street parking available all along Kapiolani Blvd without restrictions, walk was 7-9 minutes. If you get lucky, can land a spot on Ala Wai Blvd that can range anywhere between 5-25 minutes depending on where you get lucky but this tends to be busier, and same with all the in between streets. Seems like people don't normally think about parking across the bridge so I'd recommend doing that! :)
We had a small issue with the entry card getting demagnetized which Nobu was very quick and prompt in e-mailing security and getting us a new one. Overall excellent communication with the host, and would definitely stay again. If you followed the instructions and parked at Kapiolani Blvd, you can also see your car from the window for peace of mind. :)
Thanks Nobu!
