This place was priced a little bit lower than similarly-looking places (or looked much better than similarly-priced stays), so we were wary that the deal is too good to be true. We were convinced by the large number of glowing reviews. Having spent a week at Rina's condos we have no other choice but to add another positive review :)
The apartment is reasonably large; the beds are OK comfortable; the place is clean and looks exactly like on the photos; it's five minutes walking from the beach, and it's surprisingly quiet at night; you can work from there, and you can cook there. Check-in/checkout is hassle free, and Rina is very friendly and helpful.
If we were to stay in Waikiki again, we'd look for this place for sure.
