I stayed here for a month while working and it was a great experience! The WiFi was fast, and the neighbors and surrounding area were always quiet so I could get my work done during the day.
In the afternoon and evening the apartment is as close to the beach and restaurants/shopping as I could have hoped. The bus stop is right there so most things are easily accessible by foot or public transportation. There is a full fridge and stove for groceries and cooking, but my only feedback would be that you might need more pots/pans/knives if you plan on cooking any full meals.
I'd heard a lot about insect issues in Hawaii but only saw a single bug in the apartment the entire stay. David is also very responsive when I had questions before and during the trip.
