Lovely apartment with a well thought out, functional design. It's super clean. The bed is very comfortable and there are 6 pillows of different weight. We haven't tried folding out the couch, but yes - it can fold out to sleep two more people. Speaking of sleep - it is not very quiet, but I, a noise sensitive person, somehow did not have a problem with it. You will hear the waves at high tide, the nearby fountain, some traffic, sometimes music coming from the park, birds chirping in the morning and an occasional vacationer who didn't realize how much their voice carries from their balcony. The ocean must be creating white noise effect which is very soothing. Hotel has quiet hours from 10pm to 7 am.
The balcony is smaller than I'd imagine from the photos - there is just enough room for a wicker loveseat and a small table, but it has a lovely view. There are beautiful trees frequented by birds and you can almost touch a leaf if you stretch your arm out. The entrance side (a balcony-walkway of sorts) is shared by 5 apartments and does not see much traffic. It provides an excellent view of the Diamond Head (also can be seen from the window on that side) and a narrow angle of ocean view. It is enough to see if the tide is low or high and to see the boats and surfers riding the waves just by taking two steps out of the apartment. The views are really underrated in the ad!
There is an induction hotplate and utensils, pots and a pan for cooking, there is a laundromat in the building that takes credit cards. Very nice clean safe building overall. There is a patio and a lawn/garden on the ocean side that you can use for dining or relaxing. The nearest beach access is a ladder going out to the ocean. It looks more intimidating than it actually is. In low tide, it was my 10-year old's favorite swimming spot. In high tide, I didn't dare... but Kaimana beach is a 10 min walk away and has a lifeguard on duty. There is a convenience store on the way to Kaimana beach and I highly recommend checking out the Barefoot Cafe.
