We had a wonderful stay.
The treehouse was clean, had plenty of space for two people, a luxurious shower, and nice view to the sea and nearby trees. We were comfortable and happy with just the breeze through the windows, day and night. It was a nice place to return too after a day out.
Rumi put real thought into outfitting her place, like nice bath amenities, plenty of fluffy towels, a well-equipped kitchen, comfortable bed, beach chairs, etc. We lacked for nothing.
It was our first time staying in Kaneohe, and we loved the low-key, local vibe. We'd recommend a car to get the most of the location, and found great beaches a short drive away, and others only a bit further. There is a good grocery just a few minutes away, and others just a few minutes more.
Rumi is exactly what you hope for in an AirBnb host. We feel fortunate to have had the experience.
