Excellent place to stay! I'd definitely recommend it to my friends/family. I did a LOT of research on where to stay in Kailua before booking this property, and I'm so happy with my decision.
For everything you get, the price can't be beat. And, even though the location is a bit far to walk to the beach (20 minutes at least), they provide bikes (that have locks) so you can get to the beach fast. It worked out great!
Other things to note: The water pressure in the shower is very good, the outdoor shower is AMAZING (it's a real, heated shower with 2 heads, not just a garden hose on a pole), the roku player was awesome, the back porch with the birds chirping was a wonderful place to have morning coffee (which they provide, and was good!), and there was plenty of space/light.
We knew that there wasn't A/C going into it, and I was a bit unsure how that would be, but it worked out great because there is a fan in basically every single place you can put one (bathroom, kitchen, 2 in living room, 2 in the bedroom, with an extra stationary fan). Having a parking space was also a huge convenience, and something I'd say is critical in Kailua since the streets are pretty full.
Adam and Jessica are both very nice, super hospitable, prompt to respond to any questions I had before and after booking, and just generally really great hosts. I'd stay there again in a heart beat!
