Michael gives you everything very clearly through Airbnb's platform and checking in is seamless...IF you download and print off the directions ahead of time. We didn't, and retrieving it mobile-y wasn't exactly smooth. But that's on us, not him.
My wife and I were happy there because, well, it was our honeymoon, and it's a tropical paradise to be sure. The roosters do crow from early morning and there aren't windows to shut them out, but again, that's how the whole island is! The kitchen here is well stocked with dishes so you shouldn't have a problem stocking up for the week and staying in rather than head to town every night (30 minute drive to anything). A few more cleaning supplies at the ready would have been nice, but we made do and have no complaints.
What's also nice is Michael has a travel journal by the bed so you can read what sort of things everyone else did during their stay. I will recommend Kalaupapa for sure (it's the reason we came), take the scenic drive along the coast east of town, and even if you're not staying at Hotel Molokai, have a dinner there and enjoy the band!
