We stayed here for a family reunion for 7 nights. Since this was a family reunion, we occupied the whole entire estate with just around 20 people (adults and kids). The grounds of the Banyan Tree House are beautiful. There are plenty of tropical floral plants and fruit trees all around. A huge "backyard" with a couple of tree swings for the kids to use. Being in upcountry Maui, the weather was nice with cool breezes blowing all around. It was a comfort to come back to the house after an excursion in Lahaina or Kihei, where it was hot. Furthermore, the location of the place gave us that quiet, homey, laid back feeling.
The beds are pretty comfortable. The kitchen in the main house was roomy with an oven and griddle combo and another oven/stove right next to it. All the bathrooms in the house and other cottages, are all upgraded. Marty the owner was very nice and kind to answer any questions we had. He also hung a bunch of tree ripened bananas for everyone to pick and eat by the entry way of the property. This is definitely a place that I would recommend and come back to stay every time I visit Maui.
