Our stay with Love Rentals at the Waikiki Banyan was great! We stayed for 10 days and made great use of the kitchen, living and bedroom space.
Heads up - you will have to pay additional taxes after booking because Airbnb does not collect taxes for the specific location in Oahu. That was unexpected but fine.
If you'll be there for a while, I recommend bringing your own beach towels or buying there. there were only 3 or 4 white bath towels available for the stay. I loved that they had Tupperware available in the kitchen - we packed lunches for our adventures around the island. We also utilized the available Tommy Bahama chairs and umbrella a lot when hanging out at Waikiki!
The balcony and the view from the bedroom were my favorite parts. The bed was not the most comfortable but it worked fine.
Free parking was amazing since many hotels charge $30/40 per night!
