Steve and Diane's room in their home on Kula was a great experience for me.
First Steve is extremely communicative and efficient. His encyclopedic knowledge of Maui, especially Haleakala and nearby restaurants was very useful. He even dug up some AAA batteries for me when I realized my headlamp batteries were dead.
His lovely home is spotless, and the 300degree panoramic view of central Maui from the upper deck patio was truly magnificent. The bedroom is a lofted A-frame kind of space with big skylights. His property backs up to a ranch, above which is nothing but state and National Park property--so his house at 2600' is about as high up the volcano as you'll find on Maui. There's no neighbors looking down.
That said Steve & Diane's place is ideal for catching the sunrise at the summit of Haleakala and as a launching point on the Road to Hana. Staying at his place in Kula potentially saves hours on the road and was perfect for me, both for Haleakala and for starting the Road to Hana. Even driving down to Paia, Mokawao, and Pukalani to scout out dinner was fun from their place.
I can't imagine a better upcountry place to stay or a better pair of hosts to stay with. I highly recommend Steve & Diane's place for upcountry stays on Maui.
