Shane and Cha's place is in a great location and worked out for our needs. We were two couples, one with a baby, and we wanted to explore the beaches and food of Oahu with a little Waikiki tourist stuff as well. We loved that the place was near central Waikiki, but outside of the hubbub. We could easily park, walk to a beach, walk to an area with coffee and a couple cafes for breakfast, run along the base of Diamondhead, etc.
The place itself is small and there were a couple moments where it felt a little confining, but if you're not really spending a lot of your time there and mainly using it to rest in between activities, it's great. We also enjoyed the building's lanai.
