We enjoyed our time on the Big Island. We spent our time hiking and snorkeling: condo time was pretty much breakfast, sometimes dinner, and sleeping. This was an ideal location for us with easy access to both the lowlands and highlands: note that while you are within a 15 minutes of a beach, you will need to drive.
Communication with Madeline was great: she offered some suggestions on where to go for local meats and veggies.
The condo itself perfect for the two of us, and could accommodate more. Kitchen was well stocked with decent cookware: not All-Clad, but not the cheapest set for Walmart either. Stove and oven worked well.
