We had an amazing time in Hawaii, one of our best trips. This is the first time we used AirBnB in Hawaii and it was fairly good. We loved having a kitchen to make some of our own meals and it was especially nice to have some beach amenities like beach chairs and towels already there waiting for us.
The unit was a nice size and comfortable for two people but it was a bit dark and outdated inside. We did have some issues with cleanliness and a few cockroaches but it wasn't a deal breaker.
As for location, it's not exactly at or really near Napili Beach or any beach for that matter. The sunsets are nice when you go down to the front ocean side lawn but make sure you have a car to get to the beached and restaurants.
Even though it wasn't​ perfect we still think it was a good deal and worked for us.
