Can't say enough good things about this place. Perfect location - you can literally bird and whale watch right from the balcony and you're within walking distance from beautiful hiking trails.
The house had a ton of space for a large family and was very clean (I felt comfortable letting my infant crawl on the floors). The kitchen was well-stocked and the owner provided a lot of extras which we used during our adventures such as snorkel gear, umbrellas, etc.
I could go on but to summarize it was the perfect place for a group trip to Kauai and I would definitely recommend it to anyone!
