We stayed 5 nights at Hendrik's place. The listing is accurate : big room with a nice view.
Hendrik was a very helpful host : he gave us maps, directions and tips on what to do and where to eat in Waikiki and around.
Hendrik is a very welcoming host and let us leave our backpacks until the evening of our departure.
The location of this apartment is perfect, very central : beach, shops, groceries, bus stops within 5 minutes.

The only missing thing would be a living area. The lanai was great but too windy at that time to be able to stay outside and enjoy it fully.
