I was fortunate to spend 3 weeks here last month. The space is clean and well appointed and in what I think is the best location on the island. Kapa'a is pretty much equidistant from the North and West shores and is a good central spot for shopping and eating out.
Even though you can't see the ocean directly from the lanai in the condo (you can glimpse it off to the side), the unit does face east and the sun comes up bright and strong in the morning, coaxing you up to enjoy the day. Many nights I would go to sleep with the door to the lanai open so I could hear the ocean and the breezes.
As a solo traveler I don't eat out much, so the ability to prepare meals on my own is important. There are plenty of appliances for cooking in the unit: induction cooktop, Instant Pot, Keurig, electric kettle, toaster, blender, and toaster oven.
The best part of staying here for me was having the beach just a few footsteps away. It was never very crowded and I could almost always grab a beach chair. I spent many hours there reading, knitting, and relaxing -- not to mention swimming and snorkeling! (No turtles that I saw on this side of the island, but plenty of fish to watch.) If I woke up not quite sure of how I'd spend my day, I'd wander over to the beach to watch the waves and think about it.
You don't need to have a car here if you'd prefer not to. The resort is adjacent to the Coconut Marketplace where there are lots of restaurants, shopping, and even a grocery store. You can get to the Safeway and the Longs drugs in Kapa'a easily on foot if you take the footpath that goes between the beach and the resorts. A little more walking will bring you to restaurants and more shopping.
Writing this all down brings back many fond memories of the time I spent on Kaua'i. If I ever go back, I'd want to book here again.
