We spent a month here for business, and had a wonderful stay. Alyssa was the perfect host! She personally came to check us in, even though our flight was very delayed and we didn't get in until midnight. She was always quick to respond to messages, and came by to resolve any issues we had (sagging mattress, extra towels).
The unit itself is fine. The kitchen is beautifully renovated, but the pots and pans are pretty old and used. Everything else is sort of dated, but functional. Our A/C unit in the bedroom worked well, and it kept the whole apartment pretty cool. We had co-workers in the same building who had very warm units, so we felt very fortunate. The two futons in the living room were perfect for my parents, who came to visit for a week.
One sort of annoying thing was the wifi, which was very slow. It sort of worked ok if only one person was connected. My laptop was regularly disconnected after a few minutes of being online.
The building is in a great area. You can see the canal from the balcony, and the view of the sunrise from the 6th floor common area is gorgeous. The pool/hot tub area is great, and there are lots of BBQs to use. It's easy to walk anywhere you would want to go in Waikiki, but it was removed enough for us that it wasn't noisy.
Overall, I would recommend this apartment for a reasonably priced stay!
