We juuust got back from nine nights at Elizabeth's condo and my wife and I are terribly sad to be home. The condo is a short stroll from a fairly calm beach (from the building, it's just straight down the sidewalk and across the street) and we swam daily in the morning and at dusk, seeing sea turtles almost as frequently, and could have easily wiled away all of our time right there. The washer and dryer came in handy, as did the wifi, kitchen (and dish washer!), and outdoor patio (good for breakfast and lizard-watching).
The condo is also conveniently located near several snorkel rental locations, cheap and delicious eats (Da Kitchen and Moose Mcgillycuddy's, and just a few blocks from a grocery store, Starbucks, gas station, and the other lazy day essentials you might make use of. Kihei, itself, is positioned almost equidistant from every other town and shopping district on the island, which made it our first choice for this (our 2nd) trip to Maui.
What else is there to say? The building is quiet, the condo is clean, and you'll find an assortment of picnic/beach day equipment for use (chairs, an umbrella, towels, snorkels) here and there.
As is typical, staying at an AirBnB like this beats the Hell out of a resort, which puts you and your family on the wrong side of a blockade of micro-fees, staff, doors, and elevators, when all you really want to do is hit the beach, sight-see, and enjoying that Aloha spirit. I highly recommend you think about it.
