We have stayed there and are still owners of record, but we just sold our week.
Units are very clean. Bathrooms are identical and grout looks new. The bathrooms are very white. Appliances in the kitchen are nice. Cabinets are older but clean. Carpet is new and pretty, and so are the upholstered pieces in the living and dining room. Beds are comfortable. The small AC unit doesn't cool the unit as well as I would like, but I have a problem with humidity, being from Colorado and a dry climate. Consolidated/ Soleil is good at taking care of things.
The buildings are tall and there is an elevator. 2 bedrooms are the top four floors, so each 2 bedroom is two stories, so stairs on the interior of the units to the bedrooms and bathrooms.
I liked staying there. I would take an exchange in a heartbeat.
By the way, the resort reviews on TUG are not very good for Kahana Villas. Most are older reviews, and there are very few. So write a review after your stay. You will like it, I think. And bonus! Views of the ocean are pretty good from those units because they are on the top floors, and the building towers over the houses in front.
