It's all about the location! If you're looking to have a relaxing vacation on the Big Island with easy access to excellent snorkeling every day this is the perfect place to stay. Snorkeling was a priority for our family on our visit to Hawaii. We snorkeled in the morning while the water was clearest and then lounged around the house in the afternoon. We especially liked how the garden and yard was fully enclosed so we had privacy relaxing outdoors. We really felt like locals; a highlight of everyday was walking down to the water to see the sunset with the rest of the neighborhood.
The house is a bit of drive from the grocery store and restaurants. The road up to town is windy. It's best to get supplies and plan on some meals at the house. The kitchen at the house has everything we needed to prepare meals. We found that we needed to keep the windows open and fans on to keep the house from getting stuffy - especially when cooking. With the windows open, food left sitting out tended to attract ants so we had to be very careful to clean up as we cooked and put all the food away in the fridge when we weren't cooking.
There's easily enough space for a family of 4 or 5. The house is the perfect size for a small family plus a grandparent.
