Couch/dining table/kitchenette, a bathroom, two separate bedrooms. All are small, but the queen beds are really comfortable. Limited natural light except for glass doors in 1 bedroom that open onto a balcony. Some typical city noise, but balcony faces only a laid-back local establishment, not the busy street.
Entire unit recently renovated and in great shape. Kitchenette has just a two-burner range and limited counter space, but worked fine to produce breakfasts and a dinner for our group of 3. Our only gripe was it didn't have a can opener (but it has one now!).
Location is a plain building in an odd-shaped block that Waikiki's development has (so far) left behind; a mishmash of smaller buildings & offbeat establishments not frequented by tourists. It's not pretty, but you're on Kalākaua Avenue just a few blocks from where it's Waikiki's high-end shopping street, and equally close to beaches. We were able to catch buses nearby to many Honolulu and Oahu sightseeing destinations, too.
