If you like ocean views, Yen's place is excellent. We can watch the ocean and the waves crash against the shore right from the dining table. The location is unbeatable in the heart of Waikiki near the International Marketplace. Great food nearby that fits every budget (from street food and musubi to high-end restaurants).
The interior of the house is slightly dated but still very clean. The air conditioner in the bedroom worked very well during our stay to keep us cool although the one in the living room was somewhat underpowered. The check-in process was a bit of a pain—you had to first find parking (not easy to find), talk to the front desk staff (busy and curt) to get the keycards and instructions for entering the parking lot (there had to be a phone call every time entering the lot), and then drive into the lot to prepay parking, and then finally enter the building. Parking was expensive but still worth it considering the excellent location.
