We enjoyed the apartment and also enjoyed meeting Olivier and his friend (who checked us in because he was in France when we arrived.) There is an air conditioner which works great; however you do not need to use it as there is adequate air from the lanai without it. In fact the lanai was my favorite place, with a view of the golf course and the canal as well as a few hotels and some of Honolulu which are far away enough to give you some privacy. There is always a pleasant breeze on the lanai.
The apartment has everything you need to spend a nice time in Waikiki. It is close enough to the beach, hotels, buses, and trolleys, but is far enough to still have a feeling of being an apartment not a hotel. Olivier is a great host, always texting before visiting and very helpful and friendly. He is working on adding extra touches to the apartments to make your stay very nice, and will go and get anything you find that is missing. The shower and all other facilities worked great.
My only difficulty was a slight new furniture aroma which I was sensitive to (I am extremely sensitive to chemicals), but my daughter didn't notice it at all, so most people would not be impacted. I was able to air the room out by opening the windows and lanai doors. The bed is soft and the sofa (which can pull out into a double) is firm: take your pick!
