We fit four people into Koji's Waikiki studio (two couples) - though it is a smaller space, it is totally doable if one couple is willing to squeeze onto a ~full sized bed. We loved coming back here after a day of exploring North Shore or Kailua. We took The Bus pretty much everywhere and found it to be convenient from Koji's studio. The space itself was very nice, check-in/out was super easy, and Koji was super responsive. Would definitely come back if we wanted to stay in Waikiki again! Thank you!!
