Hands down the BEST experience I've had renting a vacation home. Dave takes great care of the house, and everything's clean and very well equipped (including laundry, beach chairs/towels/umbrellas, and more things you don't have to pack). The entire place gives off a warm and inviting atmosphere, and guests are made to feel like friends of the family, like true houseguests. It never feels empty - music is playing outside or people are laughing, and Dave is always around tinkering with the house (which just shows how much he cares).
I recommend this to anyone wishing to stay in Maui- the location in the town of Paia, just 15 minutes from the Kahului airport, is convenient for getting to any part of the island: the beaches around Lahaina and Kapalua for snorkeling are just an hour away, Haleakala Crater is 1.5hrs to the summit, the South Shore beaches are just over half an hour, and the Road to Hana basically starts right in Paia. I will certainly come back to the Mangolani Inn next time I'm on this island.
