It would be hard to recommend Elly's place highly enough. From the perspective of being an Air B&B host, they go above and beyond to ensure a perfect stay. The apartment(s) is enormous, with three separate bedrooms, two showers and TVs, a full kitchen, and access to their gazebo. The kitchen comes with full appliances, and all the bedding, toweling etc., is super comfortable. The kitchen is well-stocked with essential supplies (coffee, tea) and non-essential but appreciated supplies (cooking oils, condiments, seasonings etc). Elly and Sean offer complete access to their snorkeling gear (in great shape), boogie boards and cooler. This alone saves money and time.
In addition, for those who understand and appreciate the varied geography of Maui, the location is ideal. They are "upcountry," almost bang in the middle of the island just off the town of Kula, literally on the side of the epic Haleakala Volcano that for many is a primary reason for visiting the island. The gorgeous laid-back (though increasingly touristy) town of Paia is a 20-minute roll back down the hill, from where you can pick up the Road to Hana. This means the airport, likewise, is only 20 mins away. Kula has a wonderful farmers market and leads down to the island's only winery and its botanic garden too. We wish we'd had more time to enjoy Kula's cafes; we were too busy in Paia. For those who are coming to Hawaii purely for the beaches, this place may not be for you, but for those who appreciate Maui's multiple facets and enjoy that back-to-the-land organic vibe but appreciate their home comforts, this is the place.
Elly's place looks expensive on the surface, but if you were using all three rooms it would be a steal. FOr us, two parents with a tweeny child, it was actually the best price we could find for two rooms at relatively short notice towards the northern side of the island. Our only complaint is that we didn't stay longer.
