Communication prior and during arrival was great. Perhaps we were the exception, but our experience was horrible and we only stayed two nights, instead of 8. The main problem was that there was a flood in the neighbor's condo and the water leaked into our unit, making the living room and bedroom rugs very wet and smelly (also mold and mildew speed quickly given the humidity of Hawaii). The host did the minimum after being informed and actually responded in a very unprofessional manner (showing defensiveness and a lack of problem solving skills) when we insisted more be done.
Aside from this. I would say that you basically pay for the view, which is amazing. There are some nice improvements, such as granite counters in the kitchen and bathroom, but other than that, the place is funky, dusty and feels rundown. The cleaning fee is very high although we didn't see much evidence of cleanliness (hairs in the shower, and dirty rugs).
