The check-in process was very easy. Just follow the directions and you can't miss the house and you will be able to get in just fine.
Communication with Iwa is very fast. Any time we had a question, she would respond within a couple of hours.
The location is great. It is a 10 minute walk to many food trucks and restaurants. The beach is a 15 minute walk, the grocery store is 12 minutes. The town is great, it's nowhere near as crowded as the rest of the island. It's only a 30-minute drive to Honolulu. Every day that we went to the beach in Haleiwa, we saw sea turtles. Bring snorkeling gear and you will be able to swim with them.
We did see a couple of roaches and spiders in the house, but that's Hawaii. Most of the homes were built a long time ago, and they aren't sealed well enough to keep them out. We were concerned about the noise from the highway and the house being too hot (we went in July). We didn't find either of those things to be an issue. The home does have a window AC unit, which after running for a couple of hours, was able to cool the entire home.
