This was my third Airbnb I've stayed at in Waikiki (well, fourth since I immediately checked into another one due to this one not being available for my entire trip) and is my favorite so far. Yes, free parking is always a plus in Waikiki, and this garage has no assigned spaces making parking even less of a chore since you can park in any open space.
The unit itself is the largest one I've stayed in, so there's a lot of room for activities in the living room with the sofa bed put away. It's really nice to be able to sit down and face everyone while you're eating. With the bed that pulls out of the sofa, you've got two queen beds, which is great for four people. You can probably have a fifth person sleeping comfortably on the floor with the sofa cushions that are not needed with the sofa bed deployed.
There is a Toto bidet in the bathroom, but the remote was out of battery charge so we did not get to use it. We also had no way of turning off the heated seat feature. The feature itself was nice but a waste of electricity to be on 24/7.
For the shower, we had to find a YouTube video to figure out how to switch the water flow from the bathtub tap to the top/handheld tap. Apparently you have to pull down on the circumference of the bathtub tap where the water is flowing from to redirect the water flow to the top spout.
There is one washer and dryer on each floor, so you may have to wait your turn. It only takes coins or the PayRange app. For the former, there is a change machine in the lobby to convert bills to coins. For the app, your first purchase is free (washing and drying count as two purchases). It requires you to select from increments such as $10, $25, and $50 to load your account with a credit card which is less than ideal. There are smaller increments, but any amount below $10 will incur a $0.25 fee. As a courtesy to everyone else, pay attention to the time remaining for each washing and drying session and be back by the time it's finished.
Overall, we enjoyed this property and this will be our top choice for our next visit to the area. The spaciousness of the unit is invaluable and the garage is less claustrophobic than others in the area.
