Mildred's place was a great stop for the night in between two long driving days.
The place is located on a hill next to Naalehu - there is literally nothing around apart for another cottage a few yards away - basically it's only you and mother nature :)
We arrived in the evening and left pretty early in the morning, so didn't spent too much time at the place, but drinking coffee watching the amazing 360 sunrise, hearing only the roosters and the birds, was and outstanding experience.
The place is well equipped and the hosts even left a lovely self-made handbook with great recommendations for the area.
Two things to note - the hot water system is solar, so if there wasn't enough sun, the water may not be boiling hot. In addition, as said, the place is really disconnected, this can be an unique experience, but make sure you know what to expect for and arrive with everything you may need for your overnight stay. The small town nearby (very small) offers 2-3 places to eat and drink, but note that everything closes early.
