In overall the stay at Saichi's suite was a great experience. If we travel to Waikiki again, we will definitely consider staying at his place again.
He was very friendly and helpful throughout our stay. He gave us a lot of hints about restaurants and attractions and things to do and helped us a lot with our luggage and transportation.
The location was close to many restaurants and main streets and we did not have any access issues (10min walk to the beach, 15min walk to the Cheesecake Factory, 20min walk to Hilton Hawaiian beach and 25~30min walk to the zoo). The pool was clean and nice and fun to have, we used it couple of times. There is also a BBQ and a kitchenette next to the pool which was very handy. The building was quite, very clean and very well managed. The manager was always available to help us with things (On the thanksgiving day I was not able to turn the BBQ on and he was very helpful about it). Also, the neighbors were friendly and quite.
The bed mattress was firm and comfortable. The balcony was spacious with a good view. The kitchen was complete, clean and sizable with modern and new appliances plus a spacious fridge. The WiFi in the apartment was fast and reliable (we could do YouTube and Skype at the same time and had no issues).
The street is not as busy as other locations in Waikiki and is very quite (comparing to other locations). However, if you are a super light sleeper, you may wake up from the street noise a couple of times. But this is a general problem with Waikiki. I, myself am a light-sleeper and never had a sleeping problem during my stay. (Every night we were very tired from all the swimming and beach activities that the external noise did not bother us at all).
Again, we were very comfortable at his place, it was a pleasure to meet him and I suggest this apartment to everyone.
