When I did a thorough research on the Internet for hotels in Honolulu, especially in the Waikiki area, that my family of four including myself could stay at, I realized that places that look wonderful (such as those along the beach) are of course expensive, and many of the ones that seem reasonable have bad (even very bad) ratings on TripAdvisor. After shifting our search to Airbnb, I found this condo in Waikiki Skytower with excellent reviews that can accommodate up to four people and is located within walking distance to Waikiki Beach.
The building itself isn't exactly new, but this condo is very clean, and comfortable. Probably it's not that large from American standards, but it was great that the four of us could be together during our stay.
My wife and our daughter slept in the bedroom and our son and myself used the sofa sleeper in the living room. The mattress on the sofa sleeper was soft, so if you prefer hard and firm mattresses, maybe you should consider sleeping on the main bed. We sometimes used the air conditioners in the bedroom and the living room when it was hot during the day, but there was a ceiling fan in the bedroom and a good breeze at night so we usually slept with the windows open without any air conditioning (since the condo is located in a relatively quiet area in Waikiki, we could sleep without being disturbed by sounds from the streets even when the windows were open).
There are bath and beach towels and amenities in the bathroom, a beach chair and umbrella in the bedroom closet, utensils in the kitchen that is equipped with a refrigerator, a microwave oven, a rice cooker, a coffee machine, a washing machine and dryer.
The condo is on the Ala Wai Canal side so you only have a limited view of the ocean from the lanai, but the scenery of the hills of Koolau Range and the dynamic clouds compensate that. We had breakfast on the lanai with bread and fruits that we had bought the night before at one of the many ABC stores nearby while absorbing the clear morning view. On one morning, we took a walk towards Waikiki Beach through the neighborhood and had breakfast of take-out coffee and pancakes from Eggs 'n' Things (the one in front of Waikiki Beach) at a set of table and benches near the waterfront.
The parking lot stall isn't large, but even an inexperienced driver like me could park a full sized four-door sedan there so I guess it wouldn't be much of a problem for most drivers.
The WiFi worked fine throughout our stay.
And most of all, our host Tiare was very helpful and answered my messages promptly and in detail when we had questions, and she had arranged so that the receiving and returning the keys would be easy. I highly recommend staying at this condo in Waikiki Skytower.
