Clean and comfortable space, and the location was great for us to explore the island. It's less than 15 minutes to the airport, and Kapa'a is a good location that's near the midway point of the island, so you can get to either the West coast beaches and canyons or the North coast in about the same amount of time.
The apartment was clean and comfortable, and it's nice to have a full kitchen to save some money on meals here and there. The bed is comfortable, the WiFi worked well, and it was very nice to have AC on some of the hotter days. Check-in with the reception desk was very easy.
Communication with Claudia was great - she was always quick to respond and very helpful.
There is a beach/coast about three minutes walk away, though it's too rough for swimming in that particular part. For big beaches to relax and swim, you probably need to drive, but only a few minutes away by car. There's also a few supermarkets and a Ross just two minutes from the place, so you can stock up on things there. For meals, we HIGHLY recommend Coconuts - it's a local restaurant in the same shopping center as Ross, and the fish is amazing.
We would definitely stay here again, and we loved Kauai!
