I had a great 3 week stay at Mark’s Airbnb. It’s literally two blocks from the most sought after location on the busiest beach in Oahu. Everything you need is close by, and it’s a comfortable stay. The room is small and intimate, but as a solo traveler I had no issues at all. It manages to fit a desk and even a kitchen that came in handy.
I believe the whole building is temp rentals so you don’t get the odd looks you would at other Airbnb’s. Also, there are communal use of the beach chairs, snorkel gear and surf boards. A nice addition!
