As mentioned over and over again in other reviews, the carpet on the stairs and upstairs is disgusting. Shortly after we arrived I vaccuumed it myself and the dust and debris that came out was shocking. We wouldn't let our active crawling baby down on the carpet. We had a daily cockroach hunt every morning and usually found one or two - despite being meticulous about keeping the floor clean and taking out the garbage every night. The unit is along a busy road and there is quite a bit of noise from that.
However - the resort grounds and amenities were fantastic. We had dinner every single evening down at the shared pavilion, watching the sunset over the ocean. The pools and easy beach access (5 minute walk from the unit) were definite perks. I would definitely come back to Wailea Ekahi but stay in a different unit.
