The view and location at Unai's are really not to be missed. The apartment looks out onto both Diamond-head (directly) and Waikiki beach (at an angle). Waking up each morning is magical, and my wife and I saw massive rainbows almost every day. Everyone who visited was extremely jealous, even before seeing the building's public rooftop skydeck, which is accessed from the same floor as Unai's place.
The location is also great, with really good restaurants and malls (both for shopping and daily use items) in walking distance. More than just a great area to be in, it's a good area to start the day and then venture out to other parts of the island for those with a car. Several friends visited and had a great time without a car in the Waikiki neighborhood, but with a car we found it very convenient to get from here to the highway and head for the North Shore, Kailua, Pearl Harbor, or wherever.
The neighbors are also fantastic; pet-friendly buildings seem to attract some really nice folks and families. We aren't the loudest, but we never had any complaints from neighbors about noise or anything, and we never heard noise from the neighbors. Good insulation?
We had a great time at Unai's place, and we think it's a very cool way to view and visit Oahu!
