Rae's place on the east side of Kauai is a great place to stay if you want to enjoy all of the island. From Kapa'a it's an hour to the far north side(Ke'e Beach) and an hour and a half to the west (Waimea Canyon). We were able to see everything. Plus Kapa'a town has some great shops/ restaurants just a 5 minute drive down the road. (We didn't rent bikes but there were places nearby that had them available. They'd be great for getting around Kapa'a town.)
The view from Rae's place was lovely. The beach is just across the street, and, although it's not the best beach for swimming, we had fun wading there and talking walks down to some beach-side restaurants nearby. And there are some great family beaches a 10 minute drive to the north and/or south. (The beaches are all so gorgeous and different on Kauai, you don't want to stick to just one anyway.)
The condo had all the amenities we needed: full kitchen with supplies, beach gear (chairs, ice chest, snorkel gear, towels), nice balcony, pools/ hot tubs, bbq, and laundry room. It was perfect for our needs. Rae also responded quickly to some questions I had the day before we left, and she helped us with a slightly earlier check in after our flights got changed. Thanks for a great stay Rae!
