My family spent the month of June is Yasuko's flat. We were a family of 4 - 3 adults and one teenager.
Pros: Great location in Waikiki, on Ala Wai canal side of Waikiki and near International Marketplace / Rooftop amenities - pool, very nice gas grilles (3) all with a nice view / small but adequate gym / comfortable bed, good shower, strong wifi / stacked washer-dryer in unit / comes with 1 parking space in building / Yasuko quick to respond on email
Cons: Apartment is small for 4 people - much more comfortable for 2 / Sofa bed is not comfortable - when opened up it slopes at an angle / to use the television/cable you need an advanced degree in IT or computer engineering - ask Yasuko for written instructions, as we wanted to watch NBA playoffs and it was a constant battle to figure it out / parking deck has a maximum headroom of 6'2" - our van was too tall and some SUVs will be, too - you do not want to pay $3/hr in street meters, or hunt down free parking every day/night - finding a free space in Waikiki is like winning the lottery / kitchen is well-equipped with machinery, but pretty minimal supplies in unit, no foil, cling wrap, oils, spices (this may be a COVID issue), and only 2 rolls of TP / air-conditioners work well (a bit noisy), but living room unit drips water into a tub on the Juliet balcony and one must empty the tub every day - if you wait 2/3 days to empty, it will be very difficult to manage.
