This unit is a top floor unit several hundred yards from the beach (much closer to Poipu Rd than the beach) and 3 buildings in from the parking so you will be carrying/dragging your luggage a little way before it arrives at its destination.
The bathroom/bathtub is OK but a bit grimy and tired. Kitchen is compact but fine and there is a good full-sized fridge. There is essentially nothing stocked in the way of spices, cooking oil, sugar etc. so purchase everything you might possibly need on your way in if you are arriving late.
The "flat screen TV" is about the size of a reasonable computer monitor (i.e. too small by half to be considered a TV) and the TV stand was broken (the TV could be pointed down to the floor or precariously balanced pointing at an angle to the ceiling). We couldn't be bothered using the TV.
One power outlet in the bedroom was faulty.
The Internet connection was very good the unit (and from what I could tell scanning the available networks, all units) had its own cable modem & Wi-Fi so the signal was strong and the speeds more than acceptable for a rental unit.
The Kiahuna Plantation grounds are very nice and well maintained. We made use of one of the communal outdoor grills one night and it worked well and was very clean. The beach in front of the Kiahuna Plantation is very good.
There are excellent restaurants within 5 min walking (Plantation Gardens & Red Salt) and reasonable fare the other side of Poipu Rd. Pizzetta in Old Koloa Town is good and they deliver!
For those who want to explore the south side of Kauai this is a great location.
