This unit is quite convenient and comfortable for two, with a fully separate bedroom with locking door. The kids were perfectly comfortable in the living room (they put the sleeper couch memory foam mattress on the floor). The unit offers views, as well as high-quality AC. In my opinion, the space would be a stretch for four adults, but workable.
Electa was a fantastic host, offering access to some beach supplies, cleaning supplies, etc. as we needed them. She also invited us to check in early, and check in was seamless, with message sent that included a code for the door.
Parking was also super convenient, with covered walkways and a carport.
The unit does not offer any yard space for use, but that wasn't a problem in our case as we spent our days hiking and at the beach.
Overall this space worked perfectly for our family of four during our 4 day jaunt to Oahu from the Big Island.
