I had a wonderful stay at Rosalyn's ohana unit. The apartment is beautifully decorated and cared for, you can tell it was done with aloha. Rosalyn was a great host, and I had all I needed for a peaceful, relaxing stay.
You do need a car to get to beaches, restaurants etc but there's a convenient plaza just 5 min away with good food options and a supermarket. Easy drive to Kawaihae harbor for diving, or to the seaside resorts for entertainment.
The apartment itself was absolutely spotless and very welcoming. It has a kitchen with all the appliances, AC and great internet. The bed and the couch were super comfortable. There's convenient street parking or the driveway. Rosalyn was a careful, warm host and the kids are cheerful and well behaved.
I'd stay again in a heartbeat for a relaxing, chill Big island visit.
