We stayed here towards the end of August and were very satisfied with the rental! I was part of a wedding in Kapolei and the location was perfect for getting to and from bridal events on time. Everything was clean, the pictures were accurate, and check-in was very hassle-free with the keypad lock. We especially enjoyed having A/C, extra beach towels, and a coffee maker! The hosts were also very friendly and even communicated some temporary internet outage issues during our stay.
Some reviews mentioned noise- there were some footsteps above us but it was not bothersome and we did not experience dog barking. As the hosts and other reviewers also mention, the parking spot is small but our rental car was not large and had a back-up camera so it was fairly easy to park. If I could give one critique, I think it would have been nice to have some type of water dispenser or a couple of water bottles to start. We were pretty dehydrated from traveling all day so we ended up having to go out and buy a few gallons of water for our stay. If you're not too picky about tap water or plastic waste though this shouldn't a problem.
Overall for the price, I would say this AirBnB is a steal. If you're traveling to west Oahu on a budget and just need a place to sleep and shower as we did I highly recommend Weng and John's place!
