We had a great stay at Plantation Hale! It was just the right size for myself, my husband, and our 4 year old daughter. She slept on the pull out queen couch bed, and we had a room to ourselves. The kitchen had the basic things needed to do some cooking, but don't come expecting to have gourmet amenities. WE cooked about 5 nights while there and even had guests come over for a few meals. Everything was clean and well taken care of. It was nice to have the towels changed every day, and they did a full cleaning twice during our 8 day stay. The staff was friendly and helpful when we called for anything (extra blanket and cookie sheet). The Condo units are across the street from an open field. You can access the beach through the field. It's a short walk, and it makes that part of the beach semi-private since there's no resort right there on the beach. The water isn't good for swimming right there, but great for laying out and there are some tide pools for splashing/exploring with kiddos.
Overall, we were very happy with the stay and the place all around! Kapa'a is centrally located so it's easy to go north or south. However, Kapa'a traffic can be quite annoying at times!
