My wife and I stayed at Sam and Connie's apartment by the ocean for our honeymoon in Kona, and the experience could not have been better. The apartment was stocked with everything (dishes, beach stuff, ect) we needed so that we could focus on enjoying all of the amazing things to do on the Big Island. Being able to watch the sunset over the Pacific and fall asleep listening to the waves every night was awesome as well; the unit is truly on the ocean.
We would recommend Sam and Connie's apartment to anyone traveling to Kona, and hope to be able to return at some point.
