Thanks for the review! I do appreciate the feedback and I am glad you enjoyed your stay. I will check the well water filters. They may need to be prematurely changed out. The place does have a five stage reverse osmosis filter system for drinking, cooking, and refrigerator ice, which provides very good water. I will check this too. The Growlers do fly over, depending on which runway they are using. Their altitude is in the (Phone number hidden by Airbnb) foot range, but I do agree that they are loud. Hopefully they did not disturb you too much. As locals say on Whidbey Island it’s the "sound of freedom".
