PERFECT LOCATION. I would come back definitely.
This resort(Mana Kai Maui) a condo/hotel, so some of the rooms are owned(like Carol's) and you can check in to other rooms like a hotel. We had additional family members joined our trip in the last minute, so we booked a hotel room on a different floor and we had great time together!
Carol's place is a two separate units. One big room and one small room. Each unit has their own bathroom, fridge, microwave and AC, so it's really convenient. We had a one-year-old baby, and we put him down to sleep in the small room and the adults can still hang out in the big room because they are isolated.
There is an amazing beach at the back of the resort and it's literally one minute walk. Many people just walk to the beach waring swimming suits on bear foot. Carol's place has beach chairs, parasols, beach towels and beach toys, so you don't have to rent them.
It's a perfect place to relax with family.
We rented a baby crib and a high chair from the place Carol suggested(nokaoibabyrentals.com). We made the reservation on the night before, and the furnitures were already delivered to the room for free when we got there. I think they contacted Carol to get the room access. It was so convenient and cheap.
Carol was very responsive to the AirBNB messages, and there were no problem at all checking in and staying.
If you want a relaxing vacation on a Maui beach, don't hesitate to book this place!
