Thanks so much for this lovely review, Marc.
We are glad you had a nice time on the mountain, and that our mechanic friend could help with your car!
Yes, the water is brown. We have a mountain well and have it tested routinely. It is always potable, though brown in color from the sediment in the well water. We routinely change the whole-house water-filter (it can go one month, but it had actually been changed just three days before your arrival). We love the mountain water and raised our kids on it. I am sorry the color made you uncomfortable and will edit our listing to note the color and potability of the water so future guests know what to expect. It is strange...but...safe.
I should note that the upstairs is always vacant when Airbnb guests are there. We do not rent the upstairs, and only the first floor is available for Airbnb guests. I will also update the listing to be clear.
Again, thank you so very much for staying with us, and the sweet review.
