It's everything that people said it was. Very comfortable foldout couch (as people have mentioned, more comfortable than your typical foldout since it's "bar-less"... the foldout system is nearly seamless). Useful amenities, great kitchen, a good staging/storage space for beach gear.. but enough about that as the room isn't the feature.
The feature is the location. Beautiful oceanside BBQ area, quiet, respectful neighbourhood, and beach access to an amazing area for snorkeling/swimming. Abundant sea turtles, easy-to-navigate reef systems.. what an amazing place! There was some maintenance being done to the sea wall when we stayed, but we largely managed to work around it.
So if you're going to Maui for the outside environment and you're planning to use the room as an eating/sleeping/catching-your-breath type place, I would highly, highly recommend staying here!
