Maimiti's place is very clean. She clearly outlines the size of her studio. We had 3 guests and did not feel cramped. It could definitely work for 4 adults too. The location cannot be beat, you are two blocks from the main strip of waikiki. If you rent a car, try to get a small compact car because the parking lot at Island Colony is pretty tight in spacing. Parking was not included, so we paid $35 for 24 hours with in and outs. The space was well stocked with shampoo, conditioner and body wash so we didn't need to buy or bring any. Lots of hand soaps and cleaning supplies as well. Loved how stocked the place was. Would highly recommend.
