My husband and I spent our honeymoon on Maui and loved staying at Kihei Beach 405! The apartment is clean and comfortable and has every amenity you could want. The two bathrooms are very nice, even for just two guests, with all the showers after swimming in the ocean. (I don't think this profile has been updated recently - one of the bathrooms has definitely been updated since the photos were taken, and the furniture on the lanai was nicer, too.) The kitchen is well stocked with cookware and dishes, and having the ability to cook is a great option for keeping the price of a Maui vacation down. We ate in most nights and loved eating dinner on the lanai (balcony), which faces out over the water. The building also has a couple grills that we used to grill pineapple and fish.
The location is great, it's very central to a lot of destinations on the island, and a very short drive from the airport in Kahului. Most mornings we got up early and explored the island. From the condo it was less than an hour drive to Haleakala for sunrise, and a very quick drive over to Makena for scuba and snorkeling and hiking in the lava fields. It's also a great location for getting to Lahaina, Paia, and Makawao for restaurants and shopping. And there are a few great spots real close by: there's a farmer's market across the street, and a yoga studio and a great breakfast spot, Kihei Caffe, about a mile down the road. We spent most afternoons back at the condo, swimming in the ocean and enjoying the location. The beach out front is also GREAT, beautiful and not at all crowded. We even saw a sea turtle swimming close to shore one afternoon!
Also, there were definitely all age ranges staying in the building - older couples (we actually met a couple who turned out to be neighbors back home), young couples, families with kids, groups of 20-somethings. Never had any issues with noise or anything like that with the neighbors, everyone was super friendly and nice.
Oh yea, and Ali'i was also great for service. The place was immaculately clean when we arrived, and we ended up locked out at one point (long story) and they were super responsive and got us access to the unit right away.
Great place, would definitely recommend it! We hope to be back soon - would love to come for a winter stay to see the whales.
