Andre (I didn't get the opportunity to meet Susan) was incredible. He took great care of us at all hours. We had a difficult situation as we needed to work the week from the cottage and Andre made sure that we had access to a hard wire connection should we need it. He also stopped by very quickly whenever I needed some help. He absolutely made us feel at home and is such a kind person.
As for the cottage. It's a great place. The location is in a rural area, so close to the lava flow tour area. There's also an incredible black sand beach just minutes away. It felt incredible to be so close to such interesting things. There are also small farms nearby where you can speak with fascinating people and get fresh fruit and coconuts. There's ALSO a farmers market with live music on wednesdays. This place really was wonderful.
Just some notes... wifi all over Hawaii is slow. About 3Mb down and 1 up. The washer and dryer are very convenient and right outside the house, along with a convenient microwave and toaster oven. There are also snorkel and other gear you can borrow, though we didn't need to. The w/d was a lifesaver though. You'd be foolish not to book this place!
