Great place! The location is perfect to use as a base camp for all your adventures on the Hana side of Maui.
They have a washing machine and dryer so we were able to wash a load of laundry before left.
I'm a pretty light sleeper but I didn't notice the road noise at all and we slept with the windows open and only the ceiling fan going. We never used the A/C unit. This was mid-May. Not sure if it gets too much warmer in the summer months.
I'd highly recommend this place to anyone visiting Hana.
