Wow, what a beautiful property. We stayed for 2 nights because we were traveling with a 1 year old and making the trip to Hana and back in one day with a small child is not what I would call enjoyable. I wish we stayed another night because this place is beautiful.
There is no real cell service out in this area but there is a landline and WIFI. There is some beach gear out back if you want to go over to Hamoa Beach. There is a charcoal grill and tons of outside seating. I would recommend going into Hana to get food before you head to the house. Things close early in Hana, depending on the day they might not be open at all.
