A friend and I stayed here and enjoyed it. It has all the basics and is in a great location. It is off the Waikiki "strip" per se, but close enough to walk to beach, shops and the main strip. The place is as described. They provide towels, even beach towels, hairdryer, air conditioning and a washing machine is available downstairs (quarters needed). The best part is the designated parking space. The owners were easily reached on phone and helpful! They live on the premise so things/questions are resolved/answered quickly.
The most important factor for me was cleanliness which this place did exhibit. The bathroom is smaller than average but if you are okay with that, it shouldn't be an issue. There is a small kitchenette area with a refrigerator which came in handy. It can get a little loud at night with windows open but nothing out of the ordinary of city living.
Overall, if you are looking for a clean, functional place, walking distance to beach, do not forsee spending your entire vacation cooped up, do not want to spend your entire savings for a roof over your head, and do not require a frilly place, this is it! :)
