We've been to Hawaii many times and this was by far our favorite visit... thanks in large part to the accommodations. The condo was perfect - it was well-appointed and comfortable, the view from the lanai was fantastic, and it provided everything we needed to enjoy our time on Kauai (comfortable beach chairs and umbrella, snorkeling gear, boogie boards, coolers, etc.).
We absolutely loved the amenities at Lae Nani - we played tennis every morning, the pool was lovely, and most nights we cooked dinner on the grills near the pool (really nice, high-end grills!). We were surprised at how picturesque the beach is right there on the grounds. We brought the beach chairs down to the beach in the evenings to watch the sunset and enjoy an evening beverage.
The location is great, as well. There are several restaurants within easy walking distance (including a "toes-in-the-sand" beach bar/restaurant right next door). There's also a farmer's market within about a five minute walk with a good selection of locally grown fruits (great papaya!), and a few grocery stores are a few minute drive away. We also found that if it was raining at "home", we could easily drive pretty much anywhere on the island, as Lae Nani is about a 40 minute drive from Hanalei (north) a little less to Poipu (south). Both drives were enjoyable.
Ralph and Elizabeth were incredibly accommodating. They were always immediately responsive to questions, they compiled helpful info about events and things to do, and they even left us a nice bottle of wine to welcome us to the condo. Thanks Ralph and Elizabeth... we will return soon!
