Denise was a wonderful and accommodating host. The room was as promised, and the house and town of Makawao were lovely. Although the listing says there is only room for one, the bed is a standard double-size mattress (on a futon couch frame) and was fine for my wife and me.

Advice to future visitors: If you want to see dawn from the summit of Haleakala, leave the house at 3:15am. We left at 4:05am and got to the lower visitor center about 10-15 minutes before actual sunrise, but that meant we missed first light and much of what was visible before the sun crested the clouds (at which point you can't look at it any more anyway).
