We came to Hawaii for a family vacation (three adults) and stayed in North Shore for 3 nights. Dan & Ada were responsive and answered all our questions.
Pros
1. Bed is comfortable; AC is a big plus (many places I viewed in North Shore did not have AC); full kitchen, beach gear, laundry are available.
2. Daily activity credit is a plus! (we snorkeled in Sharks Cove and our rental gear were completely covered)
3. Location is great. It’s our first time in Oahu so the location was perfect for us to get to main sites in North Shore (Shark’s cove, Giovanni’s Shrimp truck, sunset beach, Haileiwa town etc.)
Cons
1. Relatively old cottage; we had a dead cockroach and small bugs crawling on the stand near TV, hot water faucet in the bathroom was hard to twist because of rust
2. Hot water was not consistent although Dan & Ada were accommodating and refunded us some credit / offered handyman to fix
3. Couch bed was not that comfortable; I’d say best is to have two people in the cottage
