This Airbnb above all has a fantastic location in Waikiki. You really can't beat being walking distance from the beach and the city center. The apartment is also only a few minutes away from Diamond Head. We loved being so close to everything.
I will say the unit itself is a little old and could do with some refurbishment, but if you're spending all your time out and about (as you should be, it's Hawaii!) it's not a deal breaker, especially at the great price. Good value overall especially if you're looking for a short stay.
