My partner and I stayed in Peter's place in December 2022, and overall had a good stay. If you want a no-nonsense place for a reasonable price, it's spot-on. Peter was also kind enough to allow us late checkout since we had a late flight.
Parking isn't too bad. There's 2-hr paid parking on the street, and some free parking on a nearby street. There are a couple parking garages nearby as well if you need to park overnight.
Pros:
Great location - very walkable to the heart of Waikiki
Comfy bed
Quiet and dark at night
Friendly and helpful building staff
The sauna is a nice perk
Free laundry (though you'll have to pay for detergent)
Cons:
Shower doesn't get very warm
Shower head is very low. Anyone over about 5'5'' would probably struggle to wash their hair.
There were spots of black mold on the shower liner.
The shampoo provided has been watered down
No beach towels to use, so bring your own or buy
No dresser space, only a small desk and nightstands
