TL;DR: To me, this is the Goldilocks of places in Oahu- just right! It is also very good value for the money (compared to most places in Oahu). If you are considering staying here, just go ahead and book!
House Decor/Aesthetics: First of all the pictures in the listing do not do justice to the place. It is much more spacious and nicer than it appears from the listing. In fact, truth be told, I was getting a somewhat weird vibe when I saw the listing, but decided to take a chance and book. And boy, am I glad I did- the place is so much more aesthetically pleasing in person (and not weird at all!). In fact, I was surprised that I actually quite liked the unique decor in the house!
Cleanliness: The place was very clean when we checked in. Unlike some other guests, we didn't see any roaches or ants at any time during our stay (I was very careful not to leave food open or leave crumbs anywhere, though).
House facilities/amenities: The house has everything you might need for a short or even a long term stay. The internet speed was good (we definitely had to login to work for short periods of time). The kitchen is well equipped with bakingware, pots and pans, etc. They did not have any sugar (I assume it is to avoid insects?) or spices or oil but if I planned to cook, I would probably just have bought those anyway. The kitchen had some interesting gadgets/appliances including a Vitamix, rice cooker, kettle, and even a coffee grinder! There were also many interesting touches/additions around the house- like a weighing scale in the bedroom, a printer (we didn't try using it, but still), etc. In fact, part of the coolness factor of the house was the interesting additions to the furniture/amenities - an actual Eames chair that we hated getting up from, a Bang & Olufsen speaker (connect with Airplay to use), and even an interesting bidet/toilet seat warmer in the bathroom. They also had a full-fledged TV but we didn't have the time to use it much. We were very very thankful for the airconditioning in all the rooms when we came back each day.
Location/Safety: The location in Waikiki was great. You can see a small stretch of the ocean between the buildings from the window, which I loved. It is <10 min walk to Waikiki beach (and Friday night fireworks at the Hilton) and many great restaurants. The area is also awesome for shopping. We loved that we could walk everywhere and not have to worry about parking. The area is sufficiently active to feel safe but not so busy that it is noisy. In fact, the place was a relatively quiet oasis in this very active area! I had been a little concerned about the building being shady based on an earlier review here- but during our stay the area generally felt safe and I didn't find anything shady about the building.
Host interaction: The hosts were very nice and gave us all the information we needed so our check-in was smooth. They were also very responsive later on when we had questions/requests.
Overall, this was a great stay experience, and I definitely recommend the place. For the price point, the place is very valuable and I would definitely book it again the next time I visit Oahu. Thanks to Wei for hosting us!
