We were booked at the Kauai Kailani. It looks very much like the photos. The unit itself is small in an older building and with a small no frills pool. It is in a great location across the street from a Safeways and Starbucks and an easy drive to food. It is centrally located so getting to Poipu, Princeville and Waimea aren't long drives.
About 30min into our stay, however, the unit lost all power.
We called Kauai Pacific Real Estate--the property manager. They were very responsive and kept in contact with us throughout the afternoon and evening by phone and text. They asked us to go out to dinner and said they would take care of the tab. In the meantime, they sent an electrician and maintenance person to evaluate the power issue. They couldn't figure out the electrical issue so made immediate arrangements for us to stay at the Waipouli Beach Resort which is about 1/2 a block away for the duration of our stay. We were in the new place by about 9pm (about 5 hours after the power went out).
The Waipouli Beach Resort was a significant upgrade. My wife's first impression "I never want to leave." In retrospect, knowing the costs of staying at Waipouli Beach Resort and Kauai Kailani, I would choose to pay more for the Waipouli Beach Resort. It had a lot more room and creature comforts which turned out to make the stay much more pleasant. We usually rent places just to sleep but the Waipouli Beach Resort was a place to relax and unwind. Huge apartment. Incredible pool with water slides. Nice gym. Comfortable beds. HUGE bathrooms with tubs.
The weather was mixed while we were at the island with some occasional wet weather and was generally cooler and very windy. Some of the normal things we would want to do--surfing, snorkeling, kayaking, Napali coast boat ride we were unable to do because of the weather. Staying at the Waipouli Beach Resort we really didn't miss them.
