Excellent location and value. I booked Can's place due to the flexible cancellation policy and convenience. However, I was highly impressed by the location and neighborhood--it ended up being a highlight of the trip.
Close enough to Waikiki to be easily accessible, but still in an interesting, local neighborhood with great shops and restaurants off of the tourist radar (which can be really difficult to find in Hawaii). The closest stretch of Waikiki is backed by a beautiful park, and is noticeably less crowded and more local than stretches of Waikiki further west.
Having a free parking spot is great, as it made it feasible and cost effective to rent a car for the whole week and explore the whole island--note that most waikiki resorts charge $40-50 a day for parking.
The apartment was spotless and very comfortable, and had everything we needed.
Can was responsive to any questions, and we really enjoyed chatting with him at the end of our stay.
I'd highly recommend Can's apartment, and would definitely stay again on a future trip.
