We loved this rental, the photos don't do it justice, its much cuter in person. Very clean and well stocked. The only downside is no AC, which is only a bummer at night because the road is loud with the windows open. We just ended up closing the windows at night and ran the fans, which was fine. They have fans in every room which is helpful.
The house is about 3 miles to groceries, and a 5 minute walk to the beach. Its about 3 blocks with a sidewalk, you have to cross the hwy but we had no issues and people drive slow anyway. The beach in the winter has a strong shorebreak, but our older kids loved getting thrashed by the waves and attempting to boogie board, they spent hours in the water. It was too strong for our little guy and he played on the beach instead. Not a beach for beginner swimmers.
Parking was easy for one car, location was great. The North Shore is crowded in the winter and everything runs on island time, but we were never more than 20 minutes from activities we wanted to do.
We highly recommend the Polynesian Cultural Center for Luau, Waimea Valley for a lite walk/hike and we drove over to Kaneohe (about an hour) to do a Sandbar tour which was also awesome, that was a great way to break up the trip and take a break from the big waves.
