We stayed at Matthew's place for over a month, and had a great time. This was one of the few properties with free parking, and given how amazing the location is, many evenings were spent walking everywhere in Waikiki without having to worry about the car!
The internet was very fast and appreciated the small amenities like Brita filter and laundry basket. I probably wouldn't stay here for an extended time if I was in a group of 3+, but for the two of us we were comfortable throughout our extended stay. Fantastic option for tourists and business travelers alike!
