I've rented places to stay hundreds of times. John was the most communicative host I've ever experienced. He definitely wants everyone to have the best experience possible. The apartment in Waikiki is extremely secure. The location is in the heart of Waikiki and just a 2 minute walk to the beach. You have several choices for restaurants. Do not rent a car, just use a ride sharing company as parking is a 8 minute walk and will cost $79/night.
Overall, I would rent from John again because of his communication skills. He is the real deal!
