Rebecca's unit has an excellent location in-between downtown Waikiki and Ala Moana. The unit is very cute and well-equipped. Communication with Rebecca was excellent. Check-in is a bit weird as you need to give all these codes to the security guard, but everything worked out nicely.
Parking was a bit of a challenge: be ready to hunt for street parking spots near the channel if you want to park for free (as weirdly, the paid parking options both on-site and off-site require you to move your car very early in the morning -- 7AM), so we opted for free parking spots and walking 5-10 mins to the apartment.
