We had a wonderful time staying at this beautiful condo in Princeville. I miss falling asleep to the sounds of the waves already! The condo was incredibly clean and you can tell it has recently been updated (great bathrooms!). The kitchen was well stocked for more than your average cooking, and we also really appreciated having the washer/dryer in unit since we got pretty muddy going out for hikes and to the beach. The lanai was also a big selling point for us - we had our morning coffee outside catching the end of sunrise and enjoyed the view of the ocean with a glass of wine in the evening.
The location was great if you're looking to explore the area. We made it to Hideaway Beach, The Queen's Bath, Hoopi Falls and Ha'ena State Park for hikes which were all within a short drive. The condo is super close to Hanalei which has a really nice, large beach and some cute restaurants and shops - just watch out for the road construction schedule if you're visiting anytime soon as this impacts travel times even with the short distance.
We did make a longer trip around the island one day and stopped for a helicopter tour (SO worth it!) in Lihue on our way down to Poipu and Polihale. Sunset at Polihale was incredible, and totally worth the 2ish hour drive back if you can plan for it (and have a 4x4 vehicle).
We had looked at a few different areas on the island before booking in Princeville, and we were very happy with our choice. Our goal in Kauai was to explore and get to see as many attractions as possible, and most of what was on our to-do list was on the north side of the island. The south side felt a lot more touristy to us vs. the north side's charm and beauty.
