Tracy is a wonderful and responsive host who is thoughtful in planning and quick to respond to needs. Her separate studio has everything you need, both spacious and well-designed. It's adjacent to her home so private but also convenient if you need assistance. Parking is on premise and safe. She was thoughtful in providing small snacks, cooking basics, and outdoor gear (e.g. cooler, 2 sets of snorkel gear, etc).
Only a few disadvantages: limited cellular service for tmobile and weak WiFi. Tracy is working on getting a signal booster though after I mentioned it. Keaau also doesn't have many street lights and the dirt roads in the residential areas can have many potholes especially after rain. It wasn't an issue for us but good to be aware.
All in all, great experience for my parents and I.
