Definitely recommend the place. The apartment is nice, clean and comfortable. Conveniently located, in a really nice complex. I agree with other guests about the bathroom door: it does not provide much privacy as it's a foldable glass door. Wasn't a big problem for us, but YMMV.
Ida gave us a really warm welcome, showing the apt and the complex (it comes with free bike rental, which we took advantage of for the awesome 4 mile bike track on the coastline) and the complimentary fruit and granola was a really nice touch.
Would definitely book again if we visited Kapa'a / Kauai again.
