Great experience - the place was perfect for our family (two adults and a 3 year old). The location is in the middle of a city, so expect city noises at night, but it is a great location - you're a 10 minute walk to most of the stores, restaurants, and beaches in the west side of Waikiki. The Ala Moana Mall is close by, in case you want to buy souvenirs or if you forgot something, with a Target and Foodland (local supermarket chain). There's a 7-11 just next door and a good coffee shop in the same building. The pool is nice and there's a park just across the street and canal. The place was clean, well-furnished, and even had some gear for travelers (mat, beach umbrella, canopy, and body board). The rooms are surprisingly spacious and the bathroom is clean and well-maintained. There are washing machines and dryers on each floor. The air conditioning works great. The unit comes with a free parking spot (hotels will charge you for this on top of their "resort fees" and whatnot, so great value).
I would definitely stay here again for trips with the family (situation would be different if it was just me and the wife).
