My family of 4 do nicer airbnb 3x/year due to my job & vacations. We've been to Oahu 10x, this was our first Maui trip. We *LOVED* this place, would love to stay every time we return:
1) full kitchen. This is key as I dislike restaurants 3 meals/day, 7 days/week. Blender for daiquiris, hand mixer for pancakes/cookies, multiple cutting boards, great knives.
2) Location was DIRECTLY across the water, balcony with a "bar" area where we sat/ate every evening watching the sun set.
3) Walk to 1 grocery store, short bike to 2 others.
4) Beach stuff (chairs, toys, body boards)
5) 10 minute walk to the more popular beach. Which is better than directly across as inherently less noisy.
6) The Benz SUV at a deep discount, and only for the days you need vs Hertz/etc where you pay 2X as much and must have the entire time.
7) Surf shop next door, lesson on water across street
FYI the third bedroom in a loft area overlooking kitchen/living room but our 18 year old used that room so was fine.
