The house is beautiful -- spotless; charming views (from both master bedroom and living/dining area); wonderfully appointed; carefully maintained. We were very comfortable/happy there. And Mary was very responsive to our questions, including pointing us to a great set of hikes (and a camping store when we had a boot problem).
The outside of the property is also lovely -- great deck, nicely set up for sitting and taking in the views; fire pit. We spent a lot of time on the deck looking at hills and the clouds. The one thing to be aware of: the house is between a set of train tracks and a busy road. You can't see either from the house (at this time of year, at least), and so the view is amazing, but you will always hear road noise when outside; and the train will come by once or twice a day, which you will hear inside.
Having said all of that, we quickly tuned out the traffic sounds while on the deck, and you can't really hear it from inside. The train takes a couple of minutes to go by, and then it's gone. My wife is very sensitive to noise, and she loved the place and had no trouble sleeping.
So, a word to the wise, I guess. But the larger point is that we were very pleased w/ the rental and would happily stay there again. It's owned by someone who obviously has both excellent taste and the desire to maintain the property at a very high level.
