We stayed here as part of a birthday weekend, and it was everything we hoped for - quiet, beautiful scenery, and a unique stay experience. The dome was well appointed, large inside, and the three bedrooms would be perfect for several couples to use at one time. The drive up from 17 is a bit steep, so go during the day. Once you've driven it a few times, it is an easy commute. Also, there is a car port right in front of the door to the place, so you'll be able to easily turn around.
The quiet here is simply superb... you are high up on a mountain side, pretty much at the top of the hill, so no traffic noise. Just the wind...
There are caretakers on site, and they are wonderful to work with. This was a wonderful experience for us, and we look forward to coming back again one day!
