Location is absolutely incredible for Waikiki - easily walking distance from shops, beach, and restaurants. The spacious penthouse unit is the only unit on its floor so you have a lot of privacy and don't need to worry about disturbing your neighbors. Just be prepared to walk up a final flight of stairs as the elevator doesn't go up all the way. The massive balcony wraps around the entire unit and has great views of the city + water. Mark was very responsive to any questions or issues that we had. I would absolutely recommend staying here - it's great for accommodating large groups.
