Had a lovely week-long stay at Sang's place in Kihei. Check-in was easy, instructions were clear, and the wifi worked great. We had no issues at all with the space - it was exactly as pictured. The two air units are both very effective (we had them on only when we were there and the place stayed fairly temperate). The water pressure in the shower is AMAZING (and the warning about the hot water is accurate - two people can't take showers back to back, so plan around that - but that comes with the territory in a condo/apartment like this). The bed is fairly firm, which we liked. We didn't use the kitchen much other than to make coffee and toast bagels. Great space!
Re: other reviews mentioning the couch being uncomfortable - Sang mentioned that a replacement couch was supposed to come before our stay but there had been some issues with shipping - honestly, it was fine. We were not in Maui to get cozy on a couch, and it served our purposes just fine.
